Research direction

Start with src/getScrollBarSize.tsx and trace the DOM setup immediately around the widthContained === widthScroll branch. Reproduce the measurement in a browser and check which layout conditions could make the values equal. Done means documenting a reproducible trigger or confirming why the branch is unreachable.

Written by the indexing model from the issue text.

Description

src/getScrollBarSize.tsx

...
if (widthContained === widthScroll) {
    widthScroll = outer.clientWidth;
}
...

的这个判断,按照上下文创建的 DOM 感觉不会触发呀,请教什么情况下会触发?
