Short description of error
Hidden geometry does not restrict the Fill brush.
To limit the fill, you need to make the surface inactive, whether it is hidden or not.

Can confirm the behavior.
This will probably not be considered a bug though (or could it?, see below), editmode selection is still considered the primary source for conversion to paint mask upon modeswitch.
Lets have a look at editmode first (and examine sculptmode later)
It is not even visibility in editmode that determines paintmask, it is always selection.
For example, take this cube:

three faces hidden
two of the remaining three faces selected
switch to texture paint mode
result: you can paint on two of the three faces

@JulienKaspar : the relevant current discussion about this seems to take place here https://devtalk.blender.org/t/paint-mode-design-discussion-feedback/24243, has there been any thought on coupling visibility (rather than - or on top of - selection)

Or... now that I am thinking more... could it be considered a bug that we have something recognized as selected even though it is invisible (I am talking about the "fail" of the sculptmode scenario desribed in the report)?
That might very well be the case, this kind of violates the "not visible = not selected" paradigm of blender.

Yes this is not an ideal behaviour. But I think Texture Paint mode was not made with visibility in mind but instead with edit mode selection, like you said.

For the implementation of the new Paint Mode it would take the visibility of the mesh into account for every operation. This is already how it works in Sculpt Mode.
So I would leave this as a known issue for now since Texture Paint mode will be replaced by the new mode.
