Open the attached test case.

Result: The text and its container <div> are rendered with drop shadow.
Expected: Only the container <div> is rendered with drop shadow.

Other repro steps (assuming the web page will remain unchanged):

1. Go to https://fr.bam-karaokebox.com/booking?city=Paris#capacity[]=10&date=2023-12-10&city=Paris
2. Click on “Capacité”

This is in fact a regression of https://commits.webkit.org/266544@main in which the drop shadow is represented as a filter style. This change did not consider they are different things and can coexist.

At the time https://commits.webkit.org/266544@main was submitted, the CoreGraphics filters was an internal feature. Enabling CoreGraphics filters by default in ttps://commits.webkit.org/268354@main exposed this regression.
