Describe your problem.

A part of the "Page Preview" popup on Wikipedia is colored incorrectly (see screenshots).

The gradient here in the ::after should go from transparent to the page background color (--background-color-base I think) instead of white (#ffffff).

To also fix this for right-to-left languages, the same should be done for .mwe-popups-extract[dir='rtl']::after with a gradient to left.
If it helps, the default of a right-to-left written article is this:

Attach screenshots.
