  Make sure line layout path gets invalidated when the mutated content is not supported
https://bugs.webkit.org/show_bug.cgi?id=254083

Reviewed by Antti Koivisto.

This patch ensures that we invalidate the line layout codepath even when the type of mutation is supported (e.g. it's all text content),
but the block container is not IFC compatible anymore (e.g. has columns).
(i.e. "shouldInvalidateLineLayoutPath" should stay true when "canUseFor" is false.)

* LayoutTests/fast/inline/non-supported-ifc-content-crash-after-mutation-expected.txt: Added.
* LayoutTests/fast/inline/non-supported-ifc-content-crash-after-mutation.html: Added.
