When clicking "Choose a file or drag it here" in the Replace Deployment dialog the OS file chooser appears. The selected file does not get set in the Replace Deployment dialog. Dragging the file into the dialog does work.

To reproduce:
Deployments tab
Choose to Replace a deployment
Click "Choose a file or drag it here" link in the Replace Deployment dialog.
Select war to deploy in OS file chooser.
Press OK.

Expected result:
File is set in dialog so replacement can proceed.

Actual result:
File is not set in dialog and replacement cannot proceed.
