No ETA for the moment, but I can confirm that it’s still under investigation, and hopefully we’ll have a fix soon!
In the meantime, could you try to change the keyboard layout to US - English (which would set your keyboard as a QWERTY-US) and see how it goes please? I know this implies quite a few changes to your keybindings, but it may help while a fix is deployed.
If needed, you should be able to save the keybindings file with your current settings, which can be found under WTF > Account > AccountName
