调研方向

先从 @tanstack/react-virtual 的测量缓存和滚动校正行为入手,然后在与附带视频进行对比的同时,复现所列出的换行行场景。仍然需要一个有用的复现;当行出现或消失时,布局不再抖动或进入无限滚动校正循环,即表示完成。

描述

Describe the bug

I think this bug is in the same ballpark to #1221:

We have a complex layout that is (for testing purposes) explicitly undersized and causes layout shifts. This sometimes ends up in an infinite loop trying to correct the scroll position and then stays stuck. Internally we've observed this on some of our playwright tests and eventually found a reproduction.

Oddly enough this behavior can be "fixed" by halting the js execution for a frame and then continue, which makes me suspect that the measurement cache or layout measurement is derived from an outdated layout box.

If necessary, I can try to create a specific sandboxed reproduction.

Your minimal, reproducible example

no reproduction as of yet

Steps to reproduce
  1. Have a layout with virtualized lines that sometime wrap lines (and therefore differ from the size in estimateSize)
  2. scroll up/down with the affected rows appearing/disappearing from the virtualized range
Expected behavior

Table layout should not jitter.

How often does this bug happen?

Every time
