`context_surrounding_text_v1` is used in KDE only at the moment and I assume you used KDE.
It sends a wrong anchor=595010448 value. I'm not sure which IBus engine you used but the error should be detected by IBus.

I was using russian transliteration if that's what you mean by IBus engine

I'm no longer using Fedora KDE Plasma edition and switched to a different distribution so I can't do any follow up reports
