This solution seems a bit fragile. We may soon run into situation where people would require conflicting thresholds for different use cases.

This would likely break if there is more padding in widget span?

Also this should probably call vertical threshold?

Yes, this fix is not a one-and-done solution, but I don't think this fix will make things worse. in #111021 and #127942, both cases the widgetspan just shifted like 0.5 pixel. This fix can resolve some existing issues. A final solution will probably be exposing compareOrder function to developers and we can follow up if there are more requests. |

I think this change is reasonable if it doesn't break any current screen order calculations. I've experienced this problem where the rects are off by a few pixels so they do not defer to horizontal comparison.

Add a threshold when comparing screen order for selectables. So when the vertical position diff is within the threshold, will compare the horizontal position.
This fixes #111021 and #127942
