Description

Here's how Fira Code looks like in emacs when set to size 13. Note the embolden selection in lower section - it looks fine.
Fira Code 13

The very same screen, but only size changed from 13 to 14. Notice that embolden selection now appears narrower than other lines.
Fira Code 14

Changing spacing and width does not help at all.

Research direction

Reproduce the issue in Emacs using Fira Code at sizes 13 and 14, with character width or letter spacing changed and an emboldened selection visible. Compare the emboldened selection width with surrounding lines; done means the widths remain consistent at sizes other than 13.
