Web editor not updating content after deleting a word (ctrl+backspace)

[Sebbones]

Summary

When deleting a word with ctrl+backspace in the web composer nothing happens.

Expected

Word is removed from the editor after deleting it with ctrl+backspace

Actual

After deleting a word with ctrl+backspace, the content of the editor does not get updated. Nothing happens visually.

The issue also occures in the editor example and current development release of develop.element.io

Problem

Internally the model of the editor seems to update properly, but the visible content does not. After pressing anything but ctrl+backspace the editor content gets updated and the deleted word is also gone (expected behaviour in the first place).

I tracked a part of the problem down to platforms/web/lib/useListeners/event.ts:205 where replace_all returns undefined after ctrl+backspace and therefore the editor content does not get replaced. I was not able to dig further into the issue due to my lacking experience in rust land.

const repl = update.text_update().replace_all;
if (repl) {
    replaceEditor(
        editor,
        repl.replacement_html,
        repl.start_utf16_codeunit,
        repl.end_utf16_codeunit,
    );
    testUtilities.setEditorHtml(repl.replacement_html);
}
