When I'm on USAA.com, and tring to export a CSV file of my bank transations, after selecting the date range, and clicking "Export" (see attached screenshot), the dialogue disappears, and the download never happens. It doesn't seem to fail to download, it just never seems to be initiated. I'm not prompted for a location to save the file, and nothing appears in the downloads list.
I've tried this in the most up to date Orion and Orion RC for Mac. I've tried every combination of safe mode, and disabling content blockers I can find.

In Safari I'm prompted for a location to save the file, and a .csv file downloads.
