Theme composer loading issue with Brooklyn Iteration 4

Something I just thought of… Take a look at this video that I posted here: https://community.skuid.com/t/theme-versioning?topic-reply-list%5Bsettings%5D%5Bfilter_by…

Doesn’t that video point to the fact that the “Update Out of Date Themes” button does not work as intended?

In theory, if I updated all of my themes, and then did a Hard Reset/Empty Cache, why when I opened up the theme did I have “unsaved changes”? By the looks of it, significant styling changes that were not updated.

Earlier I posted that:

1. Out of Date themes? Yes, after upgrading to 9.5.6 I hit the button to update. And even that page froze after updating. I knew it would take several mins potentially, so I left that open for a while, and opened up Themes in a new tab. When I saw that the button to update was no longer there, I assumed I was good to go.
Definitely something buggy with that button I suspect.
(Sorry for the triple-post. Bad etiquette :p)
