@rsese I was wondering what do the 'd', 'i' and 'v' labels mean? Just being curious.

Hey @hugoboos 👋 They're rough estimates of difficulty, impact, and visibility of the issue - this helps us think about prioritization given the team's finite resources.

Workaround:
do not declare the first key right after the dash :

Hey @rsese, Hey, I just stumbled across this issue because Github uses this downstream, but also wondered what d, i, and v were.
An idea would be to rename them to their full meanings so everyone knows what they mean? They're currently quite cryptic! 🙂
