Is there any solution?

This is actually reproducible on one of the examples - Vue Select - Ajax
Proposed PR: https://github.com/sagalbot/vue-select/pull/664
Meanwhile, if someone is having this issue in production - wrap the content of the slot with a div and prevent the click there.
<template slot="no-options">
<div @mousedown.stop="">
Begin typing to search (at least 3 letters)
</div>
</template>
this happens not only with 'no-options'. If you click on scrollbar, dropdown will stuck too.
@Pyro979 still doesn't work
Fixed by #703
@sagalbot 馃憤 Do you know when this is going to make it into a release?
@Pyro979 hoping to push out 3.0 by the end of the week. It's a major bump, but the breaking changes should be pretty minimal. So far the only breaking change will be that CSS is separate from the JS build.
