Vertical panel with height set to "custom" and resizing bar without handles

SUMMARY
I am trying to resize a vertical panel's length (i.e. its height), but when I set height to "custom" the bar that appears does not have handles.

STEPS TO REPRODUCE
1. Create a vertical empty panel
2. Put some widgets on it
3. Hit "show panel configuration"
4. Set height to "Custom"

OBSERVED RESULT
The bar that appears does not have handles

EXPECTED RESULT
The bar that appears should have handles that let you resize the panel height

SOFTWARE/OS VERSIONS
Operating System: openSUSE Tumbleweed 20241007
KDE Plasma Version: 6.2.0
KDE Frameworks Version: 6.6.0
Qt Version: 6.7.3
Kernel Version: 6.11.2-1-default (64-bit)
Graphics Platform: Wayland

ADDITIONAL INFORMATION
1. I have seen reports that this problem applies only to Wayland.
2. As I'm using a dark theme, I though that maybe the handles were invisible, so I tried to blindly search for them by looking at the mouse cursor and moving the pointer across the entire length of the bar. This way I can actually find the center handle, but the "up" and "down" handles are nowhere to be found.

Hmm, works for me with my vertical panel.
Comment 2 Cristiano Guadagnino 2024-10-10 20:30:33 UTC
Not for me. Also, I'm not the only one... see for example this thread on Reddit: https://www.reddit.com/r/kde/comments/1bfihqt/unable_to_resize_the_panel_plasma_6/
Comment 3 Cristiano Guadagnino 2024-10-10 20:41:54 UTC
It may be related to the theme.
See this: https://forum.manjaro.org/t/panel-resizing-issue-with-plasma/155812

I tried several different themes, especially the standard breeze ones (light and dark), but I always get the same problem.
See new attachment.

Comment 6 TraceyC 2025-01-29 19:32:27 UTC
I was able to reproduce the bug on git-master

I tried to reproduce using Breeze Dark and one panel, vertical on the left.
I set it to custom height. I was not able to reproduce it with this configuration.

Then, I noticed in the latest screenshot that there's also a top panel
I added a default panel, positioned it on top, and now I see the bug with the left hand panel in edit mode
Comment 7 Niccolò Venerandi 2025-03-11 17:46:14 UTC
I have tried to reproduce this as described in various ways but with no luck. If this is still happening on master, can I see a video of it please?
Comment 8 Cristiano Guadagnino 2025-03-11 19:13:27 UTC
I still have the problem, but I'm not on master so I don't think my information is valuable.

Comment 9 TraceyC 2025-03-12 15:50:18 UTC
This is still happening for me on git-master, with the Layan global theme as well

Setup:
Default panel at top
Panel fit to content at bottom
Panel on left side - custom size

Steps:
Enter config for the left hand panel
Set Height to Custom if it isn't already

Result: bar does not have handles at the top and bottom.
I'm attaching a screen shot
