  text-spacing: text-spacing-trim: Avoid character class computation when not needed
https://bugs.webkit.org/show_bug.cgi?id=281629
rdar://problem/138067688

Reviewed by Sammy Gill.

This patch avoids character class computation if it is not necessary, i.e.:
when text-spacing-trim is space-all.

We already return early from shouldApplySpacing when text-spacing-trim: space-all is set
but we are still computing character's class, which is not necessary in such case.
