[Bug] ‘Smarten quotes’ causes unexpected line break in staff labels

Hi,

I’ve noticed a issue with the Smarten quotes feature in Paragraph Styles.

When enabled, typing a straight apostrophe (U+0027) changes the visual glyph to a curly apostrophe (U+2019), but Dorico still uses the original straight apostrophe’s width for line-breaking calculations.

In Academico font, both glyphs have the same width, so no issue occurs. In fonts such as Times New Roman, however, U+2019 is wider than U+0027. Because the actual rendered width exceeds Dorico’s initial measurement, it causes unexpected line breaks in tight containers like staff labels.

(Tested on Dorico 6.2.30 / macOS Tahoe 26.1)

This might also be related to the issue discussed in this thread: [Bug] OpenType features adds extra space at the end of Japanese text

Could the team take a look into this? Thank you.
