Thanks for submitting the bugreport.
It turned out that it actually is a "feature" related to all the "help"/info bubbles related to icons and/or icon views.
You will notice that the standard MUI Help Bubble Delay is applied to e.g. Ambient's settings window help bubbles but all windows or views related to icons have a custom delay setting which is actually way shorter if you prefer to use e.g. a 5s delay.
This must have been a decision way back when Ambient was originally created.
There is currently no way to adjust this Ambient info bubble default delay setting for icon views. This might change for a future release.
