[Bug]: New menu dropdown sits above back-button for calendar

Steps to reproduce

When I have calendar open, I cannot scroll through weeks/months/.. with the arrows, because the new drop-down menu lies above the "back" arrow and thus takes precedence.
(In fact this is not fully true, because on the very bottom of the button I can still find one line of pixels that continue to work, but that is cumbersome.)

Expected behavior

The new drop-down is i.m.h.o. very debatable because now it takes three clicks to change view where previously one was enough. But if the decision has been made, the rest of the GUI needs to be adapted accordingly, at least leaving this space empty.

Actual behavior

All buttons should be accessible.

No response

Start by reproducing the calendar view in Firefox 140.0.2 on the reported Nextcloud Calendar version, focusing on the new dropdown overlapping the back arrow. Trace the calendar UI interaction that handles the dropdown and navigation arrows; done means the week/month navigation arrows remain fully accessible while the dropdown is present.
