Fix missing Add heading after fresh install, which needs a clear cache to show up in Layout editing

Thank you, Yauheni, for helping and debugging.

Your logic on this is better!

Having the better logic in the 10.0.x too.
moving the conditions in the class too.

Some Varbase ~9.1.0 sites may switch the default dashboard from Varbase Total Control Dashboard → to Varbase Dashboards → with Layout Builder

Doing the logic of only Bootstrap Layout Builder, or some front-end theme ( Bootstrap ).

I wish that Drupal has an API or some logic to let a module works only for the fron-end theme
Hoping to find a better fix for this.

Copied part of our private Slack IMs

✅ Released varbase_layout_builder-10.0.47 →

✅ Released varbase_layout_builder-10.1.0-rc2 →

Automatically closed - issue fixed for 2 weeks with no activity.

✅ Released varbase-10.0.0-rc2 →

I am not sure this is working for a fresh install.

I just did a fresh install of 10.0.0-rc2

I cannot add a heading to anything in layout builder, I get "Oops, something went wrong. Check your browser's developer console for more details."

This is what I see in console:
AjaxError:

HTTP Result Code: 500
