Steps to reproduce:
the accessible caret is rotated with the text
(Actually Firefox probably performs the best in this case. Safari on iOS shows the selection range incorrectly. Chrome on Android renders it similar to Firefox but it seems dragging its start caret would deselect everything.)
Related bug reports:
Currently, AccessibleCaret doesn't work so well with non-horizontal text. If we want to fix this properly, we should consider vertical writing-mode as well.
Also, if we want the caret to be rotated with the text, we need to make sure the usability is still good and smooth when dragging a caret, say from a horizontal text to some skewed text.
