Button Hyperlink breaks when target page title includes '/'

Versions

Confluence 6.7.2, 6.11.2 and 6.12.1
Content Formatting 6.2.5 and 6.2.6

Steps to Reproduce

1. Create a page with '/' in the title for instance: 'To be / not to be'.
2. Create another page, and add 'Button Hyperlink' macro pointing to the 'To be / not to be' page.
3. Click on the button.

Expected Result

When click on the button should redirect to the target page.

Page Example

When click on the button without '/'

Actual Result

Redirect to the page where is the button, stays on the same page.

Investigation

After inspecting the button, we could see that attribute "href" doesn't have value.

If we compare with the other button without "/", we can see the value in "href" atribute.
