Deskbar crash (reproducible)

[un_spacyar]

Hello. I found a way to crash Deskbar.I had open Otter browser, with the Otter scrollbar next to the Deskbar (see attached image).

When grab and move the scrollbar (not by the arrows, but by the slider), and continue the mouse movement over the Deskbar (click without release, like trying to drop the slider over the Deskbar), the Deskbar crash. (crash report attached too).

The weird things:

• Apparently, not happends in all the apps. I found the error using Otter.
• Also, not happends in all the Otter windows. I found it can be reproducible browsing this page:

​https://www.haiku-os.org/legacy-docs/benewsletter/index.html

• Maybe is related to the slider size?

• The first time that Deskbar crashed, I also get a launch-daemon crash. After this crash, I had to reboot. In the following cases, only Deskbar crashed. In any case, I also attach the launch-daemon crash report.
