Accessibility insights not showing children of Firefox "open with" dialog when it is opened after "File Upload" dialog

Question

Use case:-

1. Click on Browse button
2. This will open a file upload dialog - Inspect this dialog with accessibility insights - All the dialog properties and its children are showing
3. Close file upload and click on Download button to download the file
4. This will open an "Open with" dialog - Inspect this dialog with accessibility insights - Only the Dialog root element and title bar are showing. Dialog children are not showing.

Failed:-

Expected:-

When the "file upload" dialog is not opened before the "open with" dialog, accessibility insights show all the properties & children of the "open with" dialog.

We have a C++ application that uses accessibility insights API to get dialog properties and programmatically click on dialog buttons.

Windows:- Windows Server 2019, version - 1809, OS build -17763.5329 Firefox:- 102.15.1 esr 64-bit

Please help.
