“Summary The multi diff editor can leave large blank regions because synthetic empty side text models are disposed while their diff view models are still alive. Comment range prefetch resolves these models through the text model resolver. When the resulting temporary document reference expires or is evicted, the resolver destroys the underlying model despite the multi diff retaining its own independent ownership. Rendering then throws Model is disposed! ; the virtualized item latches the failure”

“A deleted file can temporarily shrink to the empty modified editor's one line height, corrupting multi diff layout and scroll position. Diff content height should account for both editor sides.”
“If a text model is disposed while a multi diff template binds, the render exception aborts the virtualization update and leaves the layout corrupted. The failure should be reported and isolated while preserving cached geometry.”
“When item geometry changes while scrolling upward, the multi diff editor anchors at the viewport top, causing visible jumps. Upward scrolling should preserve the viewport bottom; downward scrolling should preserve the top.”
