If you use the editor while the page content is not yet in the cache, everything is displayed correctly (e.g. descriptions of the buttons).
If you close the browser and reopen it again, the variables are displayed instead of the button descriptions.
If you delete the caching of the page or deactivate the caching completely, the display works again.
Example:
Open browser,
Mouse on "B" (Bold),
"Bold (Crtl + B)" appears,
Close browser,
Restart browser,
Mouse on "B" (Bold) ",
it appears:
"advanced.bold_desc",
Clear or deactivate cache,
everything OK again.

I suspect a cache problem here.
