Autosuggester popup doesn't dissapear after selecting option and multiple autosuggester popups present one over another

### Description

Initially everything works fine, but after editing certain complex SQLs containing subqueries, the autosuggester popup doesn't close anymore. I click on it and press Esc, and the focus goes back to the editor, but the popup remains.
I noticed that after clicking the popup again and then escape (multiple times, maybe 4-5), finally it disappears, as if there were multiple popups one over another. The bad popups stay visible over other apps after alt-tab!!!

When this happens, the problem is present only on the current editor. Reconnecting to the db doesn't solve the problem, but dBeaver restart does solve it.

The log shows some BadLocationException:
