v-else fails on "prod" build when preceded by an HTML comment

[marcusball]

Version

3.0.0-beta.14

Reproduction link

https://jsbin.com/vazujatufe/1/edit?html,output

Steps to reproduce

Use Vue via the embedded CDN "vue.global.prod.js" file.

Place an HTML comment block (<!-- -->) just before an element using v-else.

What is expected?

An element with a v-else condition should not be rendered when the preceding v-if condition is satisfied. HTML comments should not effect rendering behavior.

What is actually happening?

The element will still be visible even if the preceding v-if condition is satisfied.

If the comment block is removed, the v-else condition will work properly.

This issue is NOT present with the dev "vue.global.js" CDN file, as can be seen if you swap the commented out <script> tags in the minimal reproduction example.
