Input gets focus lost on cursor move

[sanatankc]

When I move my mouse even little input gets focus lost. I don't know if it is intentional or not. But it does look like bug to me.

The problem is the triggering of blur when leaving the selector as opposed to leaving the block. We need to revisit the logic of the interaction.

@walterbender, Can I help to solve this?

[walterbender]

Of course. It is all in block.js. The initial issue for the convoluted code was that for some reason there was a problem getting Firefox to update the labels in the selector blocks, hence the overzealous calls to blur. I will make a GCI task from this issue.

Thanks, that would be really nice.

I cloned the repo and I am getting following error, on starting MusicBlocks.

palette.js:31 Uncaught TypeError: Cannot read property 'classList' of null

invoker is somehow null. I tried running online version. It is running fine.

I went through stack trace and found in activity.js at line 51.

var activityButton = document.getElementById("activity-button");

activityButton is null here.

Great to have this one fixed. Thx.
