  Fixes [Bug]: Inverted app label color for light background color #38759

Summary

Instead of inverting the color of the whole app entry in the menubar when using a light background, only the color of the app icon is inverted. The invertion of the label color already happens here:

server/apps/theming/lib/Themes/CommonThemeTrait.php

Line 68 in 63bf207

'--color-primary-element-text' => $this->util->invertTextColor($colorPrimaryElement) ? '#000000' : '#ffffff',

The cypress tests need to be fixed first, I think @Hephi2 will do so later.

It is most of the time faster to compile and commit it locally :)

Thanks @susnux! But for the sake of easier backports its still better to keep source changes and compiled asset changes in separate commits, no?

I don't understand why the Cypress Tests fail here 🤔

[juliusknorr]

Restarted.

[susnux]

Locally it works. Cypress seems currently broken on CI (server master) (see all other CI runs)

I splitted the PR between source code changes and compiled JS assets and rebased. Cypress CI test issues seem to have solved themselves 🪄
