LibWeb: Do not shrink the CPU painter's corner clipping vector

Browse source 
If the provided ID is smaller than the corner clipping vector, we would
shrink the vector to match. This causes a crash when we have nested
PaintContext instances (as these IDs are allocated by PaintContext),
each of which perform radius painting.

This is seen on https://www.strava.com/login when it loads a reCAPTCHA.
The outer div has a border radius, which contains the reCAPTCHA in an
iframe. That iframe contains an SVG which also has a border radius.
