Q313: It's generally accepted that metamagic can be applied to spells from scrolls. (There's even a Crawford tweet confirming it.)

Can the Quickened metamagic be applied to cast a spell from a scroll with a bonus action? Bearing in mind that the spell scroll description explicitly says "Casting the spell by reading the scroll requires the spell's normal casting time." [1] The question here is equivalent to asking which is the more specific rule here, the Quickened metamagic or the spell scroll description.

[1] I'm told that this is errata, and that the original text explicitly made using a scroll an action. I don't have a DMG old enough to verify that.
