Does Template Toggle Theme work with .show()?

I am currently working with FastGridTemplate, but the toggle theme buttons have not toggled the theme for any of my projects on any template. In all cases, I have used .show() or .save(‘file.html’) to test my projects.

The toggle button switches sides and then returns to where it previously was. It is as if the template is not finding the theme to switch to so it reverts back to what it is already using and reloads the page from scratch (all of the plots and widgets reset state).

The toggle theme button works as expected when testing the .html version of the template loaded at Reactive tables — Panel 0.12.4 documentation.

I am currently using panel 0.12.1.
