Flex layout broken with Version 4.5.1

See original GitHub issue

The reduced Layout is that…

<div class="h-100">
	<div class="container-fluid h-100 d-flex flex-column">
		<div class="row justify-content-between header">
			<div class="col-sm-9">
				<h3>Customer Identity Management Portal</h3>
			</div>
		</div>
		<div class="row flex-grow-1" style="overflow-y: auto;">
			content area
		</div>
	</div>
</div>

html, body {
	height: 100%;
}

.header {
	background-color: #0078dc;
	box-shadow: 0 6.4px 14.4px 0 rgba(0, 0, 0, .132), 0 1.2px 3.6px 0 rgba(0, 0, 0, .108);
	color: #fff;
	height: 42px;
}

Under Linux Mint with Firefox 79 and Vivaldi 3.1.1929.48 the layout changes between 4.5.0 and 4.5.1. I have not tested it with another OS.

With 4.5.1 the small bar at the top has the height of the full screen and scrollbar appears.

Reduced this test case further at https://codepen.io/emdeoh/pen/LYNYmPR?editors=1100. Confirming this is an unexpected change. Still investigating and will see what we can do.

I am also seeing the same issue with 4.5.1 (Brave on Mac). If I change the flex line from flex: 1 0 100%; to flex: 1 0 0%; it works fine. I hope this change would be reverted - seems like a wrong thing to do.
