I am trying to: When Toolset Blocks is activated, the BLock Editor stretches to "full width" even though I do not have the Adjust Editor to Maximum Width activated.
Link to a page where the issue can be seen: hidden link
I tried this on my own test site and reproduce the problem.
I could have sworn that the first time I checked it was working, but no matter, as soon as I tried toggling the setting no amount of toggling, saving, reloading could get it to work.
I've escalated this so that the developers can take a closer look, and I'll report back with their findings.
Actually, we can consider this a usability issue we need to address. That Adjust Editor Width setting is ineffective when you have the setting shown in the screenshot enabled.
I'm discussing this with the developers at the moment, it's something we need to improve.
In any case, for now, changing that setting will respect the theme's content width while working in the backend (assuming the theme provides backend editor styles).
I don't have access to your site any more, but I installed the Blocksy theme on a test site, and it works when you have both settings applied, as shown in the screenshot.
If it is not working for you, can I get more details? What is not working?
