    IE/Edge: N/A

What steps will reproduce the problem?
1. Log into OneLogin in browser window on extended screen
2. Get Duo MFA screen
3. Select drop-down menu for 2FA device
4. Drop down menu is blank, but blank lines can be selected
5. Selected line properly displays in menu box once blank line is clicked


What is the expected result?
OneLogin DuoSecurity 2FA drop down menu will have visible list of Duo 2FA devices to select from.

What happens instead of that?
When the Duo Security box for OneLogin is shown on the primary Pixelbook display all items in the list are displayed correctly. If the same action is performed with the browser window/tab in an extended screen/monitor (Dell U2717D in this case), the drop down menu is displayed as blank. If I select one of the "blank" lines, the device will display at the top of the drop-down menu correctly.

Please provide any additional information below. Attach a screenshot if
possible.
This was working properly in the most recent update which I believe was dated June 30 for our enterprise enrolled devices.
