In T213120 it came up that non-latin fragments are (at least sometimes?) not scrolled to, in the specific case where after editing a section EditorOverlayBase.onSaveComplete updates window.location.hash and then calls window.location.reload()
e.g. https://bn.m.wikipedia.org/wiki/ব্যবহারকারী:RYasmeen_(WMF)/খেলাঘর#শিরোনাma won't scroll to the section.
However, https://bn.m.wikipedia.org/wiki/ব্যবহারকারী:RYasmeen_(WMF)/খেলাঘর#uhdhdhd will.
