I am trying to set HTML content to the title attribute of an image tag which comes from the backend like below.

```html
<span style="color:blue;font-weight:bold;"> <sup>superscript</sup> </span>
```

When I set the title using property binding and DOM sanitization, when I hover on the image it supposed to show rendered HTML but it is showing direct HTML content as it coming from the backend.

I have created the [Slackblitz](https://stackblitz.com/edit/angular-7pd4lk?file=src/app/app.component.ts) for the issue.

I really appreciate your help. Thank you for your help in advance.
