SUMMARY
Sometimes having folder sorted by size or modified causes Dolphin to use ~100% of one CPU core

STEPS TO REPRODUCE
Not exactly reproducible. A necessary but not sufficient condition is having a folder sorted by size or modified
1. Sort a folder with a lot of files by size or modified
2. Perform file operations in this folder (move to/from, delete)
3. Sooner or later, Dolphin will start using ~100% of one CPU core

OBSERVED RESULT
Sooner or later, Dolphin will start using ~100% of one CPU core

EXPECTED RESULT
No high CPU use
