Typography bugs when using vw units

I found a bug when working with typography based on vw:
• The plasmic artboard does not show the sizing correctly for some reason (screenshot 1)
• When previewing, the typography is sized correctly (screenshot 2)
• There is also an empty space that flows onto the new line after the “&” sign, which should not happen (screenshot 2)
The body font size is 1.111111112vw, based on a 1440px artboard design in Figma. Then I’m dividing all figma font sizes by 16 to convert to ems (so a 32px font in figma becomes a 2em size in plasmic)
