Julian, any tips what could be the culprit here?

Comment 5

[Julian Descottes [:jdescottes]]

The issue is related to server side target switching as mentioned in comment 2.

On target available, RDM UI performs a few async tasks:

      this.responsiveFront = await targetFront.getFront("responsive");

      if (this.destroying) {
        return;
      }

      await this.restoreActorState(isTargetSwitching);

https://searchfox.org/mozilla-central/rev/69e4ba3cbce75872d3e88ab0422fbb0198d7000d/devtools/client/responsive/ui.js#1045-1051

But we don't emit any event to know when the new target has been fully processed. And typically the setFloatingScrollbars call is done in restoreActorState.
So we should emit a test event after this.restoreActorState resolved, and wait for it in the various RDM test navigation helpers: https://searchfox.org/mozilla-central/rev/69e4ba3cbce75872d3e88ab0422fbb0198d7000d/devtools/client/responsive/test/browser/head.js#609-634

[Julian Descottes [:jdescottes]]

Thanks for the ping!

Let's file another bug. It seems that this issue comes from different a kind of navigation.
The ones we fixed here were explicit navigations & reloads triggered by test helpers such as forward, back etc...

Here it seems the reload is triggered by enabling touch simulation, while the "Reload when touch simulation is changed" checkbox is checked. The fix will probably leverage what we added here, but we will need to apply it to another set of helpers (namely toggleTouchSimulation, changeUserAgentInput, maybe simply via waitForViewportLoad on which they both rely)

Hopefully should be low frequency.
