Persistent background peeking through certain text

[npezza93]

Seems as though on v5 some text has a different background that isn't present in v4 and persists through selection.

Details

• Browser and browser version: electron 19
• OS version: macos monterey
• xterm.js version: v5 beta

Steps to reproduce

I've so far only noticed this when yarning so im not sure if v4 was just displaying text incorrectly all along and a bug got fixed.
v4:

v5:

@npezza93 do you know what's causing this background color?

Turning on logLevel = 'debug' will let you see the sequence.

Also does this happen on all renderers?

Also does this happen on all renderers?

Looks like just webgl. Canvas is fine

Heres the debug log:

Hmm, I think devtools parsing and hiding the styling sequence I care about. Can you enable the dom renderer and inspect one of the problem cells instead?

@Tyriar I'm gonna guess something to do with: #3932

Thanks, I think I know what's going on

Still seeing the different background on the lastest master:
Canvas(correct):

Webgl:

It does go away on selection now though.

Note the [1/4]and $ ./node_modules/.bin/electron .
