from the Default.sublime-theme
{
"class": "sidebar_label",
"attributes": ["transient"],
"font.italic": true
},
I think this is supposed to make the file being previewed (not opened) italicized. But this never seems to be triggered.
Maybe it’s a font issue on my system but the tabs use the same font, it seems, and there transient filename is italicized.
I see the same issue with other couple other themes I’ve tried.
