Hello,
I tried to update a Text Frame Object style to have the Text Frame Autosize Height and Width but it squishes the text box as thin and possible. But it repects the existing text without squishing when it's only Autosize Width. I've noticed it before but it's an interesting bug. I did play around with the placement reference point but it all stayed squished. Not a major bug and it could be user error on my part if there is a setting elsewhere I need to click to get it to just resize the text box to fit the existing text.
