Bug ID: 442275
Summary: Creating a folder while filtering messes the filter
results
Product: dolphin
Version: 21.08.1
Platform: Archlinux Packages
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: bars: filter

Parent folder "a" is not displayed, despite being expanded and its child
folders "b" and "b2" being displayed.
SUMMARY
While filtering on expanded details view mode, if we create a folder that
satisfies the filter as a child of an expanded folder, Dolphin will mess up the
file listing, making the parent folder disappear and the childs appear in a
buggy state without their parent being display (see screenshot).
This is a very specific bug, very difficult to explain and difficult to trigger
in normal use, but it exists and I have successfully devised a simple recipe to
reproduce it consistently. It is really difficult to explain in words, its
better to just do the steps below and you will see the bug for yourself.
STEPS TO REPRODUCE
1. Create an empty folder anywhere, named "test" (or whatever name you desire).
Open it on Dolphin.
2. Make sure you are on Details View mode with expandable folders.
3. Create a folder named "a" inside "test".
4. Right click "a", Create New -> Folder, and name it "b".
5. Expand folder "a", you should see the tree: "a" as parent and "b" as child.
6. Filter for the string "b". It should not change the view at all, since
folder "b" passes the filter and "a" is shown because it is its parent.
7. Now, with the filter activated, right click "a" and create another folder
named "b2" (a sibling of "b").
8. The bug is now triggered: after 1 second, folder "a" will disappear, and you
will only see folders "b" and "b2", weirdly linked to no parent (screenshot).
OBSERVED RESULT
Folders "b" and "b2" are displayed linked to an invisible parent.
EXPECTED RESULT
Folder "a" should remain on display, with folders "b" and "b2" as its children
passing the filter.
