Tune editor glitches when changing BPM on a tune with closed grave accents #2823
Description
If you use the built in Tune editor to edit a Tune which has a closed grave accent pair (like so:) 
the Tune editor stops working as intended. In paticular, it causes many of its visual aspects to stop working, such as it not displaying any of the insturments added after editing it, the play bar not moving when playing the track, and the BPM number not updating with the slider. Most concerningly though, it prevents you from being able to exit out of the editor via the close button, which from what I can tell effectively forces you to refresh the page to escape.
If one wants to reproduce this bug, just create a new tune with a pair of close grave accents, open the editor and change the bpm slider, then try to do something else and you should immediately see issues.
Evidence (appologizes if its a bit frantic, if requested I can maker another):

I am unaware of any work arounds other then not closing the grave accent when editing it, but that itself causes the tune function to overwrite code beneath it with itself.
The only other thing I can think of adding is that this might have a connection with the bug listed in #430 ? It might be worth you fellas checking it.
Best of luck fixing this issue, and please let me know if you need any additional info or clarification.
