What does the pull request do?
This PR removes an old workaround that mistakenly prevented the
AutoCompleteBox
dropdown from opening in certain scenarios. More context is provided here.What is the current behavior?
Previously, an
AutoCompleteBox
withMinimumPrefixLength=0
would not open when the user pressed the down arrow key with no text in the text box.What is the updated/expected behavior with this PR?
When pressing the down arrow key in an
AutoCompleteBox
withMinimumPrefixLength=0
, the dropdown will now open as expected.How was the solution implemented (if it's not obvious)?
I removed a check that was introduced as a workaround in #1570 in order to fix #1554. The underlying cause for #1554 appears to have been resolved since then, so the workaround is no longer needed.
