If Folders would show extremely cropped title, hide title.

This is an edge case, not standard behavior. This only happens when
the text / display size is at the highest level, and when a folder has
10+ page indicator dots.

Bug: 394355070
Test: Verified manually that this works well, and looks great in LTR mode and RTL mode.
