"Mark AlwaysUseComplexText as stable"
Landed in 49.0.2574.0

Confirmed by disabling the feature via command line in the affected version:
chrome --disable-blink-features=AlwaysUseComplexText

It should be noted that the feature cannot be disabled since canary 56.0.2903.0 because issue 402536 removed the corresponding feature entry.

Previously found issues for this regression were merged into  issue 677839 , which was merged later into issue 636993
