Favo's menu is different in new Firefox 151.0.0

[Pukkels]

Describe the bug

After upgrade to Firefox 151.0 (NL) there is a mixture of colours in the favo menu.
I use "Horizontal wood" theme, and now the favo pull down menu from the top is black text on a grey background, and the favo menu on the left hand side is white background and black text?.
In previous version of Firefox they where white background and black text.

It is almost similar as issue #1144
This time it is the favo pull down menu that is wrong, the lefthand favo menu is good!.

Expected behavior

Text and background as in previuos version(s)
Black text on white background

Had the same after upgrading to Firefox 151, however it's not present in Firefox 152 (Beta), so unsure if it's maybe more a upstream problem.

Here's a workaround for Firefox 151 that works for me (add it to your userChrome.css):

/* Workaround for transparent bookmark menu panel in FF151 */
html#main-window menupopup:not(.in-menulist) {
	--panel-background: inherit !important;
}

@berrnd ,

Your little patch for userchrome.dss is working very nicely.
Colour scheme is back as i had it before. (Black text on White background).
Big thanks is in place! !.

Lets hope that Mozzilla doesn't brake this in there upcoming version(s).
