Web page title in browser tab

When going to a page in the site, the title in the browser tab initially flashes "Metadata", and then changes to the loaded article title. How can we clean this up? We don't want "Metadata" to flash as the initial page title.

**Repro:**

1. Open a new browser tab.
2. Enter this URL into the address bar: https://docs.prismacloud.io/en/enterprise-edition/rn/look-ahead-planned-updates-prisma-cloud/look-ahead-secure-the-runtime

Notice that the initial title in the browser tab is metadata:

It then changes to "Look Ahead—Planned Updates to Secure the Runtime", which matches the actual page title.

The page source shows `title` is set to `Metadata`:

```
