Delete Option (pillbox) from combobox containing large list of options

Currently running 4.0.13 and finding that when combobox contains a large amount of select_choices so that the bottom of the combobox is not visible on screen, a pillbox cannot be removed from the list when clicking the ‘x’. If trying to remove an pillbox with the bottom of the combobox in view the pillbox is removed from the list. Nor script errors, but there are a number of JQMigrate warnings regarding a number of event shorthand being deprecated. Has anybody else seen this behaviour?

Issue resolved by moving from the 4.0.13 “latest” build to the most recent pre-release beta1
