TextEdit in 3d

[old merlin]

Hey guys, I've got a 2d GUI in my 3d game (using a subviewport) and for the most part it works fine (I can click the button on top anywhere) but the text edit only receives mouse input for the first couple characters on the left. If i try to click on the right side of the text i can't place the caret there and if im highlighting from the left to the right it'll stop highlighting after just a few characters (as pictured)

my screenshot doesnt have my mouse in it but the button is me being able to click on it on the right side of it

also if i type a whole bunch into the text edit until the scroll bar appears, i can click the scroll bar and use it normally
