Handle Links with URL Fragments(#) Properly

[chacha912]

What happened:

Thanks for the several useful specs added recently to CodePair.
I have encountered a small issue with links that contain fragments#.

For example, if there is a link like https://yorkie.dev/docs/js-sdk#creating-a-client, it behaves as follows:

• Expected behavior:
  • Clicking on the link should open https://yorkie.dev/docs/js-sdk#creating-a-client.
• Actual behavior:
  • Clicking on the part before "#" opens https://yorkie.dev/docs/js-sdk.
  • Clicking on the part after "#" opens https://codepair.yorkie.dev/creating-a-client.

How to reproduce it (as minimally and precisely as possible):
