(2.4.5)Is it true that button click works correctly only when the main camera is in ortho mode?

A test project is created, which the main camera is ortho:
OrthoButton.zip (822.2 KB)
the button click area seems correct (clicking the blank area wouldn’t click the button):

but when the main camera is non ortho (see another project below):
NonOrthoButton.zip (824.0 KB)
the click area of the button seems incorrect : clicking the blank area also clicks the button:


is it true that button click area is normal only when the main camera is in ortho mode?
