Multiple WebView2 instances same parent window

[ealva]

We already have an implementation that's similar to this:

ParentWnd (hosts WebView2 #1)
  |
  +-ChildWnd (hosts WebView2 #2)

ChildWnd is used to render offline pages and is shown / hidden in certain scenarios (e.g., splash screen).

We're wondering if it's OK / safe / advisable to have WebView2 #2 as a child of ParentWnd instead and if this saves us anything significant (or have potential gotchas). (This in Win32, btw).

Thank you @ajtruckle. Trying to remember the details, and this is more of a question for us early on.

We settled on a single window solution and toggling WebView2's IsVisible property to show / hide instances. This worked pretty well (for us, at least) and with less complexity than having to manage multiple window hosts.

Hope this helps others facing the same questions.
