Description
This PR fixes a possible XSS through an entity encoded select option text when converted into a FUI dropdown.
Even if
preserveHTML: falsewould prevent this, a select tag cannot contain html at all and if it contains entity encoded HTML instead, it should not be reconverted into html.The PR also fixes recreating the dropdown menu twice when no values are selected in a multiple dropdown
Thanks to @brian-codes for reporting
