Eliminate zoom jump in UV Editor (+others) when new Image added

When you make a new image, like a UV grid image, in the UV Editor (and most likely elsewhere, you fill in the blanks), the window zoom jumps (or DOESN'T jump, but appears to) to accommodate the new bitmap.

This is jarring . In dev terms, it's a 'paper cut'.

For a smoother user experience, it would be good if adjustments were made behind the scenes such that the UV outlines remained the same screen size, with the new image superimposed behind the UV outlines.

It's not really a bug, but it's very distracting and unpleasant, needlessly.
