What is the expected ratio for button with icon only

[wiibaa]

Hello,

we are currently evaluating our application behaviour in the context of accessibility with custom browser user-settings like the font size.

While the button looks square in standard design they change quite a bit with different font size, see screnshots below.

Could you please confirm that this the expected behaviour or not ?
Thanks you in advance

Medium

Large

Very large

Small

Hello, thanks for this feedback
We will check with the designers, but I assume that the button is supposed to stay square.
Currently the min height and width are defined differently (one in rem, the other in px), and this is why it changed ratio. We will update to have the same unit here.
