GUI for manipulating muscle paths clips the names of frames and resizing the window does not effect

[lks-dev]

Steps to reproduce

1. Open a Model
2. select a muscle in the navigator plane
3. select [...] on the muscle's path property
4. try to select a different frame from the options in drop down

Expected result

being able to read and differentiate between all options.

Actual result

on macOS longer frame name/paths are clipped and not readable/differentiable:

on linux/pop_os the same issue is even more problematic as the clipping of the options starts sooner, making the dialog completely unusable:

As shown in the screenshot resizing the pop-up window does not solve the problem.

Environment and GUI version

macOS - binary install opensim 4.5
Linux - popOS, build with adapted install (treating pop as ubuntu) scripts from:
CORE_BRANCH="f81e7c3dbbe60986f5e8d5c978951be1e9736000" # 4.5.1
GUI_BRANCH="4fe7a0fba93b43cb1d73133d0aea1a56df54b8de" # main on 08.10.24

Thanks for reporting, the issue dates back to the time when we migrated from using body names (typically short) to full paths (much longer) a few years ago. Will take a look to see what it takes to fix.
