URL's with special characters don't work when opening in new tab in general activity feed

At the moment i'm facing a minor issue with the general Activity feed page:
companyname.atlassian.net/wiki/discover/all-updates

We use [] brackets in our blog titles. 
The url that is created for these pages, do not contain the brackets.

If I open one of these links from the general activity feed in a new tab, the url that is linked to, contains these brackets. This causes a 400, "page does not exist" error message.

If I click on the link directly the url works perfectly.
Also opening a new tab from a space with the recent activity widget, works like it should. 

So the issue only seems to happen when opening pages from the general activity feed page in a new tab.

OS: Windows 10
Browser: google Chrome 80.0.3987.87

additional information. when opening a page from a space activity feed in a new tab, the brackets are translated to ascii codes in the url:

[ = %5B

] = %5D

In the general activity feed page they are literals.
