Incorrect Appearance of Bolded Fonts in a Font Family

Issue type

Engraving bug (incorrect score rendering)

Description with steps to reproduce

1. Select a font that has a family with multiple weights/styles (Here is Sitka - Sitka Text);
2. Type anything (Here is under Tempo text. So far the problem has been seen in text type Tempo text, Title, Expression/Staff text — likely affects all text elements) and have it bolded by toggling tab "Properties";
3. Notice: When the zoom level ≤202% (Fig. 2 & 3), the characters are added with an outline; when greater, the outline disappears (Fig. 4). The appearance characters' with an outline doesn't match their expected "Bold" style (Fig. 4, captured in Windows 11 notepad).
4. See also issues #31602, #33693.
