Stylus: CSSLint / Stylelint options - error modal is unresponsive

[stonecrusher]

FF64.0
Stylus 1.5.2

When trying to modify the Stylelint preferences, I got an error (legitimate, for wrong syntax).
This error popup/modal (#message-box) is unresponsive despite having z-index of 9999990.
If clicked, the underlying Stylelint preferences (#help-popup) reacts. I can't close / confirm the error and therefore can't save the style or continue work.

Same with other message-box modals in that context, like "Discard the changes?", "Invalid JSON format" etc.

Maybe related to stacking contexts

/edit
The linter prefs themselves seem to have problems. Even changing a true to false gives me an error...

Can anyone reproduce? Just change some Stylelint options and you'll see.

Yeah, I could reproduce. It seems like there is an overlay on top of it (z-index thing maybe?). I just haven't had time to look into it.

Weird pointer-events issue. Should be good now.
