When writing the cm6 plugin, I found that tiddlywiki did not optimize the input method editor. With the help of the composing event, I solved the problem of the cm6 plugin very well.
However, in tiddlywiki, each input box did not optimize the IME. Every input Updates will be triggered, such as the search page, tags input interface, etc. Although for editors, throttling is used to control the refresh of the preview page, it would be more appropriate to add composition events for further optimization.
I tested it on your website and found that it had no effect because you only judged the ime status in validateSelection. Here are some minor changes I made.
For input boxes created by js, developers can easily control them through code, but for ordinary wikitext created html search boxes, this is not easy to do, so it is easier to make tiddlywiki core support this
