Description

Having bold + italic text does not work when at the end of a string (example 3):

***I'm bold and italic!** I am just italic.*

*I'm italic. **I'm bold and italic.** I'm also just italic.*

*I am just italic. **I'm bold and italic!***

Expected:

I'm bold and italic! I am just italic.

I'm italic. I'm bold and italic. I'm also just italic.

I am just italic. I'm bold and italic!
