Last time I checked the version Electron used by Discord was severely out of date causing several issues that had been solved months ago upstream. That’s the fault of Discord, not Electron but there are several issues with Chromium that I have to deal with on every Electron app I use. Compose sequences are still partially broken. I reported it at Chromium but they responded with a video of them testing it on Windows (not with a VM), said they couldn’t reproduce the issue (with a Linux specific input method?!) and then marked it as unreproducible.
