[Problem/Bug]: External File Drags are blocked while a modal dialog is open #5198
Description
What happened?
If a modal dialog is open, in my case a file selector, I don't get any drag events in the web layer when dragging a file into the window, either from the modal file selector itself, or my desktop/an explorer.exe window.
This is allowed in Electron, so this feature reduction could interfere with some users workflows.
Importance
Moderate. My app's user experience is affected, but still usable.

Repro steps
Using the WebView2WindowsFormsBrowser example, add:
window.addEventListener("dragenter", e => { alert("Drag Detected!") }); document.getElementById("openFile").addEventListener("click", e => { window.showOpenFilePicker(); })
to AppStartPage.js, and add:
<button id="openFile">Open File Selector</button>
to AppStartPage.html.
Then run the solution, click the "Open File Selector" button, and attempt to drag a file into the window and you won't see an alert.
