[24.0] Fix activity bar touch events on iOS devices

[mvdbeek]

I'm not sure what the issue is here, the minimal fix is this:

diff --git a/client/src/components/Popper/usePopper.ts b/client/src/components/Popper/usePopper.ts
index ad18847d8d..183d2e49be 100644

@@ -190,7 +190,7 @@ export function usePopperjs(
                 on(referenceRef.value!, "mouseout", doMouseout);
                 on(popperRef.value!, "mouseout", doMouseout);
                 on(referenceRef.value!, "mousedown", doMouseout);
-                on(popperRef.value!, "mousedown", doMouseout);
+                // on(popperRef.value!, "mousedown", doMouseout);
                 break;
             }

but I think we can probably just rely on events happening on referenceRef.

This also happens on an Ipad, and the fix works there as well.
