300k px canvas but Parameters capped at 32k

You can create a 300,000 px canvas but when you go to the Parameters and try to manually enter coordinates X/Y on an object below 32,000px, it auto resets the X or Y to 32k, unless you move it manually. Which is awkward for a huge a image.

Why?
Why allow for a 300k canvas, when using manual coordinates breaks it?

Is there a fix or setting to stop this from happening?
Large Canvas seems pointless at this minute.
