IDEA 2020.1 Losing the cursor after showing quick definition and then jumping to it without closing the popup

Steps to reproduce:

1. Navigate to a symbol, select it in the editor and press ⌥Space.
2. Open the definition without closing the popup, press ⌘⏎.
3. Press ESC to close the quick definition pop-up
4. Now the focus of the cursor is lost

(here's a demo video)

I haven't found a nice way to re-focus again on the current editor window - an ugly workaround is to open and close for example the project window (2x ⌘1).

Any IDEAs? 🤔
