Selecting "Relative" canvas size forces zeros

I'm not making this a bug . . .  yet. Is this how PS always worked? I have not used Photoshop (now at 26.8.1) in a long time, so maybe my memory is simply flawed.

 

On any file, select Image > Canvas Size. It starts with values in the width and height fields. The "Relative" option should be off (at least, it is on my Mac). Finally, enable "Relative".


PROBLEM: The Width and Height fields change to zero.


At least I THINK that is a problem. What I mean by that is I could swear by my left lung that the numbers did not become zero. All that option would do is keep the size ratio the same by making the adjustment of one field automatically adjust the other field.

It is correct when selecting relative. The zeros simply mean add 0 to height and 0 to width. You then change the numbers to the addition (or subtraction with a negative number) that you require.

"A picture is worth a thousand words". Simplifying the question is helpful to search previous records. This is the question. 

 

When Relative is ckeck marked why Width & Height is zero.

As explained in the answer above, it means add nothing and take nothing away - so, as initially set, no change.

" Is this how PS always worked? "

Yes, as far as I can remember that dialogue.
