Is there a way to switch off the delay before icon and dropdown menu are shown next to filename in Preview.app?

In Big Sur, the unified toolbar of Preview.app shows the file name, but not the icon and drop down menu next to it, unless I move the mouse onto it. This always creates a slight delay of about 200-300 ms and makes it really difficult to establish a good workflow when re-filing pdfs through drag and drop or renaming files, for example.

Is there any way to switch this off and see the file icon and dropdown menu all the time?

Here is an example of what I would like to see permanently and not only when I hover over the file name with the mouse:

The officially recommended solution is to press and hold shift key, which will cause it to appear instantly when you mouse over it.
