Canvas Size experience is basically broken in 27.5 release

The recent 27.5 release got updated Canvas Size modal, and it has several bugs that affect my workflow, which requires gradual pixel-perfect changes of canvas size in various directions (my units are pixels most of the time).
I use relative changes to canvas size, so ‘Relative to current dimension’ checkbox is ON for me most of the time, and in this case the bugs I get are:

1. Canvas Size modal opens with default values of width and height set to 1 pixel. Should be 0.
2. The width and height inputs do not accept 0 value — it gets reset to 1, meaning if I want to change canvas size in one direction, anyways I’ll get 1 pixel added to the other.
3. It’s not possible to set negative values now, which used to work before, and at times it’s more convenient and precise way to ‘crop’ canvas, rather than using the Crop tool.
4. The values step now is 0,01 pixel, which is meaningless in most scenarios. It used to be 1 pixel, and it should be, as it allowed to use keyboard up and down arrows for quick pixel perfect adjustments.

See attached video demonstrating all 4.

What I discovered later: if I uncheck ‘Relative to current dimension’ checkbox and check it again — I get the right behaviors (except bullet 4 with increment step). Those all are apparently bugs to be fixed.
