This may be related to or even causing #1284 (comment) !
Perhaps the G1 commands should be there and contain some crucial step preventing beginnings of bridging perimeters becoming too thin or outright starting in mid-air whole millimeters after edge.

From https://github.com/prusa3d/PrusaSlicer/releases/tag/version_2.4.0-beta2 change log:

Empty G1 commands were sometimes present in the G-Code due to the cooling slow down logic. This is an old bug present in 2.1.0 already #3058 #5176

The previous occurence of empty G1 was fixed with 4e9f906
