Width setting should have priority on height

In my point of view, height setting in pixels is irrelevant and should not be shown in the UI
Maybe some users are not agree with that, but in this case the width setting should have priority on height value.

Common example : I want 1024 pixels width resizing, the aspect ratio is not my problem. I leave height setting as it is, but if the height value is too low, the image size will be less that I was especting (1024 pix width)
