If you have a Select component with typeahead and start typing, it displays the options as expected. Clicking tab and then shift-tab to go back however doesn't expand the list

In fact, this issue happens any time you tab to get to the text input rather than clicking

Version: "@patternfly/react-core": "^3.16.10"

Repro steps:

1. Have a Select component with typeahead variant that's not in focus
2. Tab until you get to text input in the Select component
3. Start typing for a result

Expected result:
Options list is expanded

Actual result:
Nothing happens
