Description of the Issue

Existential Quantifier Symbol (∃) sometimes not being displayed

Steps to Reproduce the Issue

1. Create a new Tab
2. Copy the Symbol "∃" as the very first Symbol. It will be displayed as a square symbol
3. The symbol will display correctly if a different symbol follows. Pasting the string "∃∀" will display the existential quantifier correctly

Expected Behavior

The Symbol "∃" will always display correctly

Actual Behavior

The Existential Quantifier Symbol can only be pasted when it's part of a longer string.
