Just looking at some Chromium and TinyMCE bug reports and I’m suspicious. However Safari is based on WebKit.
Two other questions-
- are you seeing the same problem when editing Collection items in the collection item pop-up window?
- is all of this happening on the same computer, but works ok on other computers?
- do you have another computer on the same network that you can test?
These are just theories, but one of the things I’ve noticed is that the “broken spacebar” issue only happens when I’m blogging at cafes, which often have unusual network & firewall configs. Seems possible something is getting blocked or revised.
