Is there any way to control the default height of the widget controller panel when in the mobile layout?
By default the panel has a height of about 150px:

The user can then drag it up to around 50% or 100% height of the map widget, tapping on the title does the same.
The default height is not very usable and I'd like it to open to 50% by default. Is this possible without customizing the controller widget?
