Hi @Alejandro Gomez,
Thank you for the code example. I can reproduce this issue as well. Actually, this issue does not only occur in Kiosk mode, but also InPrivate mode. Interestingly, Kiosk mode also uses InPrivate mode, so this can be related to some sort of problems with InPrivate mode and Windows touch keyboard.
I can also reproduce this issue in Chrome (both Kiosk and incognito mode). So, technically it seems to be related to all Chromium browsers. Unfortunately, AFAIK there's no workaround to this issue. I suggest you create a post for Chromium Dev Team: https://bugs.chromium.org/p/chromium/issues/list.
For Edge Dev Team, you can send feedback by Alt+Shift+I in Microsoft Edge.
