Earlier today I upgraded one dev environment to WEF 220.127.116.11 by adding the FixPack.
Now I find that in 18.104.22.168 the 'Use Theme' checkbox in Data Page doesn't honor the .uitheme file. Instead, the values in the HTML Template and Style Sheet Override fields are getting used regardless of whether or not the Use Theme option is selected.
I have confirmed in the App Tree that the Theme file being used is my custom one and that the override.properties file is pointing to the right theme file.
Any chance this feature is broken in WEF 22.214.171.124? I plan to upgrade another VM to see if I get the same problem.
