Can't change spelling in Discord

I'm unable to update the spelling of a word in Discord. I get the squiggly line under the word then click it. I get the dialog box with the thress suggestion but when I go to click on one of the suggestions it never selects. This will be Discord for Mac version 0.0.407 on 2019 MacBook Pro running macOS 26.5.1 (25F80). Harper works just fine in everything else (like editing this post). I have tried closing, reopening both Discord and Harper to the same effect.

Reproduce the issue in Discord for Mac 0.0.407 on the reported MacBook Pro and macOS 26.5.1 setup. Start by checking whether the suggestion dialog appears and whether any suggestion can be selected; done means a displayed suggestion is selectable in Discord while Harper continues to work elsewhere.
