Html tags shown up on page

Hello support, how are you?

I am a fresh new French user and I have seen a display issue showing a miss-closed tag on the url:

https://bitbucket.org/account/user/bastianb/plans-and-billing/

On this page in the first rectangle for Plan under 'Changer de dépot' (en: change repo?) we can see '">Gérer la facturation' (en: Manage Billing ?)

It does not allow us to click on the button 'Gérer la facturation'; I have then sort it in major problems - I don't know if it is working for English viewers, that's your part of investigation

I also have provided a screenshot to show you

Do not hesitate to contact me back if you need more details.

Thank you !
