            Bug ID: 509016
           Summary: In details view, clicking the expand arrow for a
                    specific folder cycles the view to Icons
                    (DynamicView=true bug)

SUMMARY
In a folder looking at details view, if I click the expand arrow next to the
folder names, in general it expands the folder to show the contents in a tree
structure. However, in a folder with 32 subfolders, when I click the expand
arrow for one specific folder, it does not expand the folder but instead cycles
the view mode to Icons. This is confusing because my intuition is "huh it
navigated away and entered the folder instead of expanding it", but clicking
back alas does not bring you back, because on closer inspection it changes to
view, not navigate away. This is also annoying as you lose whatever state of
expanded file tree you were inspecting.

Turns out this is the result of "Use icons view mode for locations which mostly
contain media files" (DynamicView=true in dolphinrc). Disabling this results in
the arrow expanding/collapsing the folder as expected.


STEPS TO REPRODUCE
1. Viewing a folder with 32 subfolders and no files
2. The subfolder that the bug triggers on contains 2 folders, 100 files (mostly
png, jpg).
3. It could be related to "Use icons view mode for locations which mostly
contain media files" - I have that checked in settings.
4. Click the expand arrow for the folder in question

OBSERVED RESULT
- clicking the expand arrow for the folder changes the view mode to Icons

EXPECTED RESULT
- Expand the folder, not change view mode

Or I'd possibly even expect it to navigate into the folder with Icon view, but
I'd prefer it just expand the tree and not do that.
