We develop traditioanal mongolian to chinese dictionary on web site.

Confirmed in IpadOS 16.7.5.

I’m also a reader of CJK who *needs* vertical-rl and vertical-lr for combined Phags-Pa.  Phags-Pa and Mongolian and Manchu… all perpetually broken in WebKit.  Im *begging* you all to fix this layout stuff for vertical text!

Can you try with Safari Technology Preview 188 - if you have macOS because it has following fix:

>> Fixed incorrectly oriented Traditional Mongolian script characters. (272454@main) (93426525)

It fixes both Mongolia and Phags-Pa.

STP188 vs Safari 17.3

It seems to be fixed.

@Elika - I am suggesting to mark this as 'RESOLVED CONFIGURATION CHANGED', any suggestion before I do so?

Additionally, it seems that the fix is also in Safari 17.4 beta as well so hopefully if you update to iOS 17.4 or iPad 17.4 in future, it will be fixed:
