screenFrame is read only but can't set it? There is weird behaviour if you set it?

[vennsoh]

Despite setting screenFrame x position to 100, it is still showing 15 as I print it?

print(element.screenFrame.x) // 15
element.screenFrame.x = 100
print(element.screenFrame.x) // 15

But if I do,

print(element.screenFrame.x) // 15
element.screenFrame = {
x:  100
}
print(element.screenFrame.x) // 100

However the width, height and y will be defaulted to 100, 100 and 0.

Weird?

I thought it will behave similar to .frame
