Issue with Virtual Select

This repository contains files to reproduce an issue with the virtual select feature when setting an empty list of options.

Steps to Reproduce

1. Open test.html. Initially, the list of options is searchable in the multiselect.
2. Click on the removeall button. This will empty the list of options.
3. Try to use the search feature. It will not be usable due to the absence of any entries.
4. Click on the fill button. This will repopulate the list of options.
5. Try to use the search feature again. Despite the presence of entries, the search feature remains unusable.
