No highlighting for custom_attributes in title template

[RuslanHryn]

Put a template to get custom attributes into the title.
For example:

{{ notification.custom_attributes["some-key"] }} separator {{ user.custom_attributes["some-key"] }}

and no values from attributes will be rendered in the title.

No issues if use the same template in the content.

Also, {{ notification.custom_attributes }} separator {{ user.custom_attributes }} will be rendered correctly in the title. The problem is that getting value by keys is not working properly in title only

Hi Ruslan,

The tags do work there; they're just not highlighted. Sorry for the inconvenience. It's been on our radar, and we will fix it rather sooner than later.
