Bug 497729

SUMMARY
I use dolphin with "Remember display style for each folder" selected in the settings, that works as expected. However starting with the version 24.12.0, it suddenly changed the default view when it isn't modified for a folder to ALWAYS "Icons" and there doesn't seem to be any way to change this default, even when using "View > Adjust View Display Style..." menu. This breaks my workflow, where I expect all folders to open with details view I preconfigured, except those I manually modify, this way I need to manually change to details mode EVERY time I enter a folder for the 1st time.

STEPS TO REPRODUCE
1. Use options "Remember display style for each folder"
2. Go to "View > Adjust View Display Style..."
3. Configure a custom view different from the original one (e.g. Details view) and make sure to check "Use as default view settings"
4. Open some directory without custom display style

OBSERVED RESULT
The "Icons" view is ALWAYS used by default, despite attempts to configure a new default one.

EXPECTED RESULT
The previously set view, using the "Adjust View Display Style..." menu, should always be in use when there isn't a different view manually modified by the user.
