Problem description

While using a screen reader, if I click a link, the previous page meta title is read, instead of the current/new page. This is confusing to a user.

Steps to reproduce:

1. Navigate to home (about.sourcegraph.com)

2. Turn on your screen reader.

3. Click into Request a demo button link.

4. Notice "Sourcegraph | Code Intelligence Platform" is read first, instead of "Request a Demo | Sourcegraph".

5. Navigate to (about.sourcegraph.com/code-insights)

6. Turn on your screen reader.

7. Click into Request a demo button link.

8. Notice "Sourcegraph | Code Insights" is read first, instead of "Request a Demo | Sourcegraph".

Expected behavior

As a user utilizing a screen reader, I expect button actions to focus on the correct next item so I understand my action was completed. When a link is clicked, the current/new page meta title is what should be picked up by screen readers.
