Voracious Hydra trigger not showing up, need to click on screen to activate it

So I was playing some draft decks I made against bots, and it was taking a huge amount of time for the bot to process my hydra etbing (or so I thought), but then I just clicked on the screen for no reason and the trigger popped up. Don't know if this problem is only against ai, I would assume so since I couldn't find any other issues mentioning it.

No source file, test, or entry point is named in the issue. Reproduce a draft deck containing Voracious Hydra against a bot, then trace why its trigger appears only after a screen click; done means the trigger becomes available without that click.
