Trying to decide between error message summary format.

First has message at top. Page would scroll up on form submit.
Second has message show right above buttons.
Button container sticks to bottom of screen on scroll.
I like the message showing right above buttons because you'd see it right where you clicked but concerned it would cover too much of the page, especially on mobile.

@hill The first one is a more bulletproof pattern because its sticky button bar has a fixed size and it covers less content. Multiple errors + potentially long error descriptions + sticky surface + small screens = a dangerous combination (you might leave no visible content area on small screens).
