Incorrect text positions for some font

[JorjMcKie]

Description of the bug

The attached PDF page uses a font which ascender value is incorrectly determined by MuPDF.
Basis of this post is Discussions post #3772.

How to reproduce the bug

The revealing command is mutool draw -o test.xml -F stext test.pdf.
test.pdf

The problematic font is "AdvOT144a03c1" (embedded subset).
Note that this error happens in MuPDF, not PyMuPDF. So we assign the label "upstream bug".
However, PyMuPDF's Page method get_text("dict") does not correctly repair the computation when setting TOOLS.set_small_glyph_heights(True). So we also assign the label (PyMuPDF) "enhancement".

PyMuPDF version

1.24.9

Operating system

Windows

Python version

3.12

@JorjMcKie This has been fixed upstream, can can be marked "fix developed", right?
