mtlcl410andClaude Opus 5.5 5307510f66 M3: copied and found text keeps each combining mark after its letter (view.copy-text, view.find) ...

Text drawn one glyph per show operation, with zero-advance Thai tone marks
starting a hair past their base's advance, came out with the mark after the
next letter ("ห้อง" read "หอ้ง") because a line's glyphs were sorted by x
alone. A combining mark (Mn/Me) of a left-to-right script drawn right after
the glyph it sits over now rides on that glyph: placement sorts clusters, so
the mark keeps its content-stream place. Word gaps are measured between
clusters, and the tight-cluster rule now guards only loose combining signs,
so a Thai or Indic word gap with no space glyph reads as a space.

Fixes #6517
