Cosmetic filters containing pseudo-elements do not show results in manual/interactive selection mode

[SSoulaimane]

Tank you for implementing cosmetic filters with pseudo-elements in the last rc #2448.

However in the manual selection mode when a cosmetic filter with pseudo-elements is entered, no result is shown, it shows the number 0 at the corner bottom of the input box and the 'create' button is disabled.

But still the filter works when manually entered in the user filters tab in the settings.

It's not possible to querySelectorAll pseudo-elements, so it's not possible for uBO to programmatically find them on the page.

I see, then I suggest the element whom the pseudo-element relates to be the one shown in the match, then the preview should work as :style() does, and the create button should be enabled.
