Description
Commands such as getting the inspection text and activating a particular particle seem to no longer work after some of the sidebar changes on macOS. This needs to be diagnosed and fixed.

To Reproduce

1. Run AmoebotSim.
2. Instantiate any algorithm.
3. Try to get the inspection text of any particle by Alt+clicking on a particle; nothing appears.
4. Try to manually activate a particle that can do something by Cmd+clicking on a particle; nothing happens.

Expected Behavior
Getting inspection text and activating a particle should work as described in the usage guide.

As of today, @jwweber and @josephbriones have both confirmed that this is still an issue.
