Bug on create new tab

When "Remember display style for each folder" is enabled, opening a new tab in
Dolphin (or opening folders in new tabs from external applications like VS
Code, JetBrains Rider, or Zed) causes file and folder icons to fail to render
in "Details" and "Compact" view modes.

The text labels remain visible, but all icons are completely invisible until a
manual zoom level adjustment (e.g., `Ctrl + Mouse Wheel`) or window resize
forces a layout/viewport recalculation, after which icons render immediately.

This issue does not occur when "Use common display style for all folders"
(`LocalViewProps=false`) is selected, nor does it affect "Icons" view mode.

STEPS TO REPRODUCE

1. Open Dolphin → Hamburger Menu → Configure → Configure Dolphin... → View
→General.
2. Select "Remember display style for each folder".
3. Set the view mode to "Details" or "Compact".
4. Open a new tab (press `Ctrl + T` or open a folder in a new tab from an
external app).

Or `kwriteconfig6 --file dolphinrc --group "General" --key "GlobalViewProps"
--type bool false` + prior step 4.

OBSERVED RESULT
The new tab loads in Details/Compact mode, but file and folder icons are
invisible/missing. Adjusting the zoom level or resizing the window forces the
icons to reappear immediately.

EXPECTED RESULT
Icons should render properly immediately upon opening a new tab without needing
to change the zoom level or resize the window.

SOFTWARE/OS VERSIONS
Operating System: Fedora Linux 44
KDE Plasma Version: 6.7.4
KDE Frameworks Version: 6.29.0
Qt Version: 6.11.2
Kernel Version: 7.1.13-200.fc44.x86_64 (64-bit)
Graphics Platform: Wayland
Processors: 12 × AMD Ryzen 5 5600G with Radeon Graphics
Memory: 32 GiB of RAM (30.6 GiB usable)
Graphics Processor: AMD Radeon Graphics

ADDITIONAL INFORMATION

* Only affects "Details" and "Compact" view modes; "Icons" mode renders
correctly.
* Workaround 1: Switch back to "Use common display style for all folders"
(`kwriteconfig6 --file dolphinrc --group "General" --key "GlobalViewProps"
--type bool true`).
* Workaround 2: Slightly change the zoom level in the affected tab to trigger a
re-render.
* Tested with a clean profile (`XDG_CONFIG_HOME=/tmp/test dolphin`) and
confirmed that the behavior only starts once `Remember display style for each
folder` is checked.
