  [IFC] Disable partial layout when replaced box with relative dimension(s) is present
https://bugs.webkit.org/show_bug.cgi?id=278407

Reviewed by Antti Koivisto.

Unlike other inline content, boxes with relative dimensions (e.g. width: 50%) are marked dirty right
before layout (see RenderBlockFlow::layoutModernLines and the commit message in 240772 at main for more info).
Unfortunately such boxes skip the normal IFC invalidation flow which may cause incorrect rendering.

Let's disable partial rendering for now when seeing boxes with relative dimension(s).
