Anyone else finding (in Sandboxes) that when overriding the Account New button with a visualforce page under lightning it is showing the page rather compressed? ie only displaying 1 line of the page layout...

Seems to be an issue with Winter21 Patch11 where they have dropped the height attribute from this css class -

.oneRecordActionWrapper {

  border-radius: .25rem;

  height: 100%;

  background-color: var(--lwc-colorBackgroundAlt,rgb(255, 255, 255));

}

Adding back the height attribute seems to resolve the issue...

Got a case open with SF - 28076735 but still waiting for someone to respond.
