Following the plan of action, we have created a new governance proposal to fix the problem on Aave v2 Polygon.
Voting will start in 24h.

Considering governance times, if approved, the fix will be applied in approximately 7 days from now: 1 day of delay to start voting, 3 days of voting, 1 day of timelock on Ethereum and 2 extra days of timelock on Polygon.
