Remove absolute positioning on validation error messages

[mikejolley]

This PR removes the absolute positioning on error messages and fixes #4715. This reverts a change in #3968 which did this to prevent the button press issue. After making this change I did the testing steps in #3968 and could no longer replicate the issue on Chrome or Edge, so this may have been a browser issue that has since been resolved?

Fixes #4583
Fixes #4715

Testing

See steps in #3968 for button issue (test for regression)
See steps in #4715 for styling issue

@ralucaStan can you test this your side and confirm it no longer occurs?

Changelog

Fix validation message styling so they never overlap other elements.
