Unexpected behavior of annot.set_rect() with carets and strikeouts #4755
Description
Description of the bug
annot.set_rect() sets the rectangle incorrectly with certain caret annotations. It appears to usually be off just a few points.
Also, attempting to set the rectangle of a strikeout annotation produces the message
cannot set rect: code=4: StrikeOut annotations have no Rect property which it as the very least not true in my example: I successfully retrieve its rectangle.

The annotations came from Foxit PDF Reader, which is maybe related to the issue (nothing goes wrong on a pymupdf inserted caret, which can be seen in the entire bug-result.pdf), but that's just a guess.
