   - Placing a Word 97-2003 `.doc` document works out each style's formatting once and each property run's once, and refuses property pages that are out of order, listed twice or overlap, a style sheet that holds fewer styles than it counts, styles based on each other in a loop, and more than 100,000 runs of character or of paragraph properties, 16 MiB of properties or 100,000 paragraphs, hidden ones included (`file.place`, `crates/engine/src/tests/textimport.rs`).
   - On the desktop, File › Place reads and decodes files off the UI thread, one at a time, and places each once it is read, with "Placing" in the status bar and the busy spinner until then: the Place dialog's OK, a file dropped on the canvas, a click or drag of the place cursor, and the OK of the PDF, DXF and text import options. The files and thumbnails the place cursor is loaded with are read the same way, and the Place dialog's lines about its files are read on a thread of their own. Files are placed in the order they were started; a file is not placed while a dialog is open or a drag is under way, and a file whose document was closed meanwhile is not placed. `file.place` and `file.place.queue` over MCP and scripts reply as before.
   - On the desktop, Paste from a menu or shortcut captures another app's bitmap or reads a copied image file on the UI thread, then decodes the image on the file-reading worker. The status bar shows "Pasting" until the image is pasted. Windows device-independent bitmaps and Linux clipboard images are encoded as PNG on that worker. A Copy or Cut made while the image is read keeps its internal clipboard. `edit.paste*` over MCP and scripts reads the bitmap at once.
+  - File › Revert also drops what was started for the content it discards: a file being read for Place, for the place cursor or dropped on the canvas, a bitmap being read for Paste, and a paste waiting at its Swatch Conflict dialog are not placed or pasted in the reverted document, and the status bar says the document was reverted. Edits made while a file is read, a Revert that fails or that a batch rolls back, and a Revert of another document leave the read to finish as before (`crates/ui-egui/src/placing/tests.rs`).
   - The pixels of a PNG, JPEG, GIF or WebP file that Place decodes to check them are kept in the image store the renderers share, so the canvas's first frame with the placed image draws them without decoding the file again on the UI thread: File › Place, a file dropped on the canvas, a click or drag of the place cursor, `file.place`, and Paste of such an image. A CMYK JPEG is still decoded when it is first drawn (`crates/ui-egui/src/placing.rs`, `crates/render/src/tests.rs`).
   - A photo whose EXIF orientation turns or flips it (a camera held upright or upside down) is placed and opened upright, as it was taken; the image is stored as it is seen (#4284). A quarter turn swaps the resolution's axes, so the image keeps its physical size. TIFFs read without the image decoder (grayscale with extra channels, CCITT Group 3, CMYK with one plane per ink) follow their Orientation tag too, and a turned CMYK JPEG or TIFF keeps its inks, 8 bits each, as a CMYK TIFF.
   - SVG import shows a raster `<image>` whose EXIF orientation or TIFF Orientation tag turns or flips it upright, linked or as a data URL, and inside an SVG shown as an image: the pixels are stored turned, the width and height swap, and the `<image>` box fits the turned image under `preserveAspectRatio`, as CSS `image-orientation: from-image` describes (<https://www.w3.org/TR/css-images-3/#the-image-orientation>). A turned CMYK JPEG or TIFF keeps its inks as a CMYK TIFF, as does a CMYK TIFF that is not turned. TIFF data URLs (`image/tiff`, or untyped TIFF bytes) are read, and TIFFs with an alpha or other extra channel, CCITT Group 3 TIFFs and CMYK TIFFs stored one plane per ink are read as Open and Place read them. The pixels are decoded within the decode allowance, and a TIFF claiming more strips or tiles than the decoder can count is refused before it is decoded (`crates/svg/tests/it/image_orientation.rs`).
