Bitmap emoji fonts do not render #15925

Describe the bug / provide steps to reproduce it

Fonts such as the Samsung Emoji font can be selected as fallback fonts, but emoji render as unfilled rectangles rather than displaying the actual emoji glyph. The font in question is a .ttf containing bitmap symbols (fc-query states outline: False(s) and scalable: True(s)). The font is accepted in the font settings and listed in the acceptable values for those settings.

If I install a SVG-based emoji font, such as Noto Emoji, then that font will be used regardless of preferences.

Environment

I don't believe this is the same as #12629 because the font in question is a .ttf, but possibly there is some overlap.

I have tried this with many kinds of fonts, and it is consistently broken. We use emojis in markdown docs quite a lot, and my main use-case for using zed would be note taking and markdown editing.

System: Arch Linux, latest + Zed 0.149.3 (installed from arch-extras)
