Revert "fix: fixed font sizing issue after applying elm theme"

[eemaanamir]

Reverts #1228

The font size issue is consistent across MFEs and should be fixed in the Elm theme. This MFE-specific fix creates inconsistency, and without the Elm theme, it makes the font size too small and affects readability.
