Thank you for taking the time to report this issue!
Thanks for filing. This is probably another RDM tunnel-related problem, whereby RDM (Responsive Design Mode) should forward the page style action to the inner viewport through its tunnel, rather than letting the action apply to itself.
Priority: -- → P3
I was looking a bit into this and went far enough to understand the solution, so I'll push a patch here.

Comment on attachment 9030714 [details] Bug 1500921 - Tunnel the pagestyle message through RDM; r?gl! [Beta/Release Uplift Approval Request] Feature/Bug causing the regression: Bug 1305769 User impact if declined: This isn't a new regression. The new RDM was implemented 3 years ago, and enabled for real 2 years ago (in bug 1305769). This limitation with the Page Style menu has existed since then. If we decline this fix on beta, then people who use the Responsive Design Mode and who try to select styles from the Page Style menu won't see these changes affect the page displayed in RDM. Instead, the changes will affect the RDM UI itself. In particular, they won't be able to turn off styles on the current page. This probably represents a small fraction of Firefox users though. Is this code covered by automated tests?: Yes Has the fix been verified in Nightly?: Yes Needs manual test from QE?: No If yes, steps to reproduce: List of other uplifts needed: None Risk to taking this patch: Low Why is the change risky/not risky? (and alternatives if risky): RDM works in a way where it creates a sub-iframe inside the current tab, and it relays all actions from the browser to the nested iframe (like when you navigate to a different page, instead of the new page replacing RDM, the message is relayed to the inside of the iframe). So this fix simply adds handling for the page style messages, so that they, too, are relayed to the nested iframe instead of applying to the RDM UI. String changes made/needed:

[Triage Comment] Allows users who use the Responsive Design Mode and who try to select styles from the Page Style menu to see these changes affect the page displayed in RDM. Thanks for including an automated test with this, though I still think some extra QA verification would be good here as well. Approved for 65.0b6.
