Height range modifier on first layer removes bottom solid layers above modifier

[user1419]

What happened?

If using a height range modifier only for the first layer, then the layers above are not solid but filled with infill.

I have a print with text on the bottom layer and to prevent the slicer from producing a ton of tiny "islands" inside the letters which are really hard to get to stick to the printbed, I am using the setting "Perimeters loop" inside of a height range modifier for the first layer only. To avoid having a lot of visible seams on the side of the print, I want that setting only for the first layer.
As a workaround I made the modifier for the first 3 bottom layers, but I would prefer to only have it on the first layer.

This can be caused by any height range modifier that intersects any layer with top or bottom solid infill, and all the modifier settings that I've tried. It impacts both the 2.4 and 2.5 branches. I've attached an example which demonstrates the problem.
