If you're using Google IME, the IME is located in the lower left corner of the window. (MS-IME was the correct placement)
I also tried with Beta14 and the Google IME was positioned correctly. In other words, it's a bug that's happening in Beta15.
The same applies to input fields such as search boxes.

### Minimal reproduction project

It doesn't depend on the project and happens when using Google IME in the beta 15 editor.
