Track following when closing an info box

[mfpx]

There is an issue with track following when opening an info box by clicking on any of the options on the right hand side. The current stage selection gets reset whenever an info box is closed while a track is playing.

To reproduce:

1. Create a track and enable track following (Preferences > Auto Follow Track)
2. Play the track and wait for it to get past the first stage (<1st box in the grid at the bottom)
3. Click an option title on the right hand side to open an info box
4. Close the info box before the time marker reaches the end of the stage
5. Observe. The track following will be reset to either the first stage or a random one for the duration of the current stage

Once the time marker reaches the next stage, track following works as intended.

Expected outcome: Track following should not be affected by the invocation of info boxes

Information boxes have always been a bit wonky as they use undoes in the change history to close the prompt, thus moving the currently-hovered-on pattern around. I don't expect any good fix for this unless these prompts use a different way of closing, or a more intricate fix is found.
