fix: preserve non-maximized config for autohide panels/docks

[ryanabx]

This PR fixes the behavior of autohide panels/docks when a maximized window is focused.

Previously, the panel/dock would expand itself to the edges, regardless of whether the setting is turned off in the settings. While this is appropriate for regular panels, autohide panels/docks should not expand to edges unless it's set that way in settings.

Thanks, I believe the original design is that the dock and panel both extend when a window is maximized, so I think this needs approval from @pop-os/ux, unless it was already approved in a thread on mattermost

[ryanabx]

It was not pre-approved, so we will wait and see what UX thinks!

From my subjective view, the dock shouldn't automatically extend if it's an autohide dock. I believe it matches behavior on other systems with floating autohide docks

Edit: clearer wording

[maria-komarova]

We may have missed that particular case in the original design so I'm fine with the suggested changes to not extend the dock or panel that are set to autohide.
