SUMMARY
Akregator uses QtWebEngine to render feeds, but those don't close even after
closing akregator properly.

2. Check processes using ps aux | grep webengine and ps aux | grep akregator

OBSERVED RESULT
ps aux | grep webengine

akregator

EXPECTED RESULT
Only grep process should be shown. When I close falkon, there is no such
residue of adChromium. Akregator should work similarly
