Redstone ore doesn't turn back on if it turns off while mining it

The bug

When walking on redstone ore, it lights up, which is normal. The exact moment it went out, I happened to start mining it with an iron pickaxe and it didn't light up.

How to reproduce

1. /gamerule randomTickSpeed 1000
2. Start mining redstone ore
3. It lights up, then turns back off
4. It doesn't turn back on as you continue to mine it, unless you start over
