New Instrument View Strange Component Display for Grouped Data

[andy-bridger]

Describe the bug

I found this testing #40830 but it was unrelated to that so thought i'd put it here. I loaded a focused ENGINX dataset for testing as that happened to be the last thing I had loaded. I hadn't seen the new Component tree so had a look around that and found that highlighting certain components behaved a bit erratically

This seems to be due to each spectra only corresponding to a single rendered point in the display, but some branches of the components tree being split across groups

To Reproduce

I can send the specific dataset if needed but I think it should be fairly straight forward to reproduce

Expected behavior

I guess when component branches are split like this I would expect all the related detector groups to be highlighted rather than just reverting to showing everything

Platform/Version (please complete the following information):

• OS: [e.g. Windows, RHEL 7, Ubuntu, macOS]
• OS Version:
• Mantid Version [e.g. 6.0.0]
