Invert selection command shifts the current selection

I select my thing using Flood Select Tool then click Invert Pixel Selection and it shifts. Happens every time but not for a new document.

If you have a bleed set for your document then this is a known issue.
I think the current ‘workaround’ for that is to remove the bleed, do the selecting, and then re-apply the bleed.
