Standard BA crash when clicking BA cancel button while executing MSI with visible UI

[wixbot]

Environment: Windows 2012 x64, Wix v3.9
Using standard BA with a customized theme - executing a chain with 7 packages (Exe+MSI)
The second package in this chain uses DisplayInternalUI ="yes".

While the MSI UI shows - click the BA 'Cancel' button (shown behind the MSI UI - yet still active.
This causes the BA to freeze and crash.

BA Log ends at: "Applying execute package"

MSI log shows error:: Failed to create a window for the dialog DlgCustom!
The installer has encountered an unexpected error installing this package. This may indicate a problem with this package. The error code is 2884. The arguments are: DlgCustom, ,

Windows event log: The program Setup.exe version 1.0.0.0 stopped interacting with Windows and was closed.

Hope this helps!

Click the BA 'Cancel' not the MSI UI Cancel..

This occur only when clicking on Cancel when PrepareDlg is shown - or when executing SpawnDialog event from another dialog. Clicking cancel will raise the BA cancel dialog over the MSI UI
When MSI showing a 'static' dialog the cancel button does not pop up and the MSI gets focused and everything works fine

1. Doc WixStdBA isn't a good DisplayInternalUI host.
2. BalExtension could issue warnings to the effect of No Download #1.
3. In WiX v4, revisit the whole issue.

Release changed from v3.9 to v3.x
