Firefox: Non-alpha chars are not monospace in Monaco editor #171
Description
Describe the bug
For some reason, only alphabetical characters are monospace in the editor. According to the devtools, other characters use Noto Sans Arabic, while alpha characters use Noto Sans Mono. This also seems weird, since --monaco-monospace-font doesn't include either of those, but that's what it appears to be.
I tried this in Firefox on a fresh profile, which had the same issue. Chrome worked as expected.
Screenshots/logs
Both of these lines have 5 characters in them, but the one with all the punctuation is much shorter.
Additional context
My client OS is Linux, specifically a variant of Fedora Silverblue.
Tracing Info
