I am logged into JIRA Cloud and I already have the issue I'm linking to open in another tab.
I paste the URL to this (or any other issue) into an Office document
Clicking on the issue presents a page which makes it appear as if I'm not logged in, as below:

After logging in from this page I see the issue, but it makes it tedious when working from a table of issues in Excel when none of the links work in one click. In all other regards I can access JIRA normally in this browser (Chrome).
