Combobox list will not appear until focus is removed off the browser tab.

[Ebony2000]

I am having a problem with the combobox, where if I open a new instance of the browser (in my case Chrome), fill the combobox with a list of items, and press the down arrow, the list will not appear. The text box is displaying the first item in the list, but the list will not appear. To get the list to appear, I have to remove focus off the tab in anyway.

Example:

1. Create a new tab.
2. Click on another application.
3. Click on the desktop.
4. Press F12 to bring up the devtools.

When focus is lost on the tab, the list automatically pops open. Afterwards, so long as the browser stays open, I no longer have an issue. I can close all tabs, and reopen the page in a new tab and have no problem with the combobox. The issue only occurs the first time the component is used after a new instance of the browser is opened.
