fix: workaround for "thread context was already set" exception

[piotrkwiecinski]

Fixes "thread context was already set" exception triggered on every popup display.

The proper fix is going to be more involved and is tracked in #2080.

I'll pick it up at some point in the future. It's going to require reworking a JDialog implementation to DialogWrapper. It will be more time consuming from implementation and testing point of view.
