Unfortunately we’ve discovered that icon positioning is in largely the same boat as multiscreen positioning prior to Plasma 5.27: it’s sort of fundamentally broken by design and requires a re-write to prioritize robustness and simplicity of design. So until that gets done (probably for Plasma 6.0) it’s likely that this stuff will keep happening. 
There are many many causes.
