v-bind href in <a> tag doesn't work with complicated setup

[WangHansen]

Version

2.6.8

Reproduction link

https://jsfiddle.net/khydf31a/

Steps to reproduce

Put the href with subject and content for <a> tag in a data and use :href instead

What is expected?

For tag to open email client with prefilled content and title, v-bind:href should return the same result as just using href

What is actually happening?

When using v-bind, content of email is ignored

Same issue with sms:?&body=something

HTML encoding is only required if you literal values in HTML directly. You don't have to encode the value in JavaScript. Make the following changes and it should work.

- mailto:?subject=test subject&body=test content
+ mailto:?subject=test subject&body=test content
