Describe the bug
This issue exists in the dev and v3b3 release. I missed this.... 😔

When the polarization dropdown in the spectral profiler is "current", the displayed profile can be updated according to the selection in the animator via the polarization slider. However, if we use the polarization dropdown in the spectral profiler to explicitly select a computed component such as Pangle, the profile is incorrect and seems to be the same as the "current" which is Stokes I. I compared the protobuf message and it seems the backend returned the same profile as the "current". The requirement appears correctly set by the frontend. @markccchiang @TienHao Please help on checking this issue and identify which side the issue sits.

To Reproduce
Steps to reproduce the behavior:

1. load a stokes cube
2. launch a spectral profiler
3. use the polarization dropdown of the spectral profiler to select Pangle
4. the profile stays the same as the "current" was
5. set the polarization dropdown to current and use the animator polarization slide to switch to Pangle to see the correct profile

Expected behavior
Setting the polarization dropdown of the spectral profiler to, for example, Pangle, should result in identical profile as when the polarization dropdown of the spectral profiler is current and the polarization slider of the animator is Pangle.
