Mobile Menu: Border radius of menu at 0 during Ease In / Out transition

I’ve added a border radius to the mobile menu component when the menu is open. I have the menu set to drop down with an Ease transition effect.

However, during the time of the transition itself: the border radius of the menu component does not display the border radius that I added. Only when the transition is complete does the border radius show.
