Message about dependent extensions when installing an extension uses "key" instead of label
For example when you install stripe, you get
x
Extension Upgrade Failed
You will not be able to install/upgrade com.drastikbydesign.stripe until you have installed the mjwshared extension.
Now try to find "mjwshared" to install it. If you don't already know that that's called "Payment shared" you can't find it. I think this changed when the extension screen stopped showing the keys which wasn't that long ago, but I wouldn't really call it a "regression".
The second variable $extension is just a string so at first glance the label isn't readily available and it might need to do some kind of lookup.
