In fact, I am more concerned about the bug of this editor, although few people edit tiddler on mobile phones
PS: Although TiddlyWiki has some test cases, for this kind of web application, it’s always hard to cover all possible scenarios due to various issues. Regression bugs may occasionally occur — and sometimes they might go unnoticed for a long time.
This has nothing to do with codemirror
See: Chrome on iOS text editor RSOD for my previous notes on this issue. Can confirm, not a code mirror issue: I don’t use that plugin.
