Description
Resolves #11259
Popovers that start open weren't receiving a reflow due to the isOpened flag only being set on mutation "mud-popover-open". Now it properly checks on connect if a popover should be open. Most popovers force a reflow due to changes as it's rendered but some don't is why it was not a widespread problem.
How Has This Been Tested?
Visually in WASM and BSS.
