Merge branch 'fix-compatibility-with-ie11-for-merge-requests' into 'master'
Fix compatibility with Internet Explorer 11 for merge requests
## What does this MR do?
This merge request restores the compatibility with Internet Explorer 11.
## Are there points in the code the reviewer needs to double check?
No.
## Why was this MR needed?
Commit ca3c0c6cd915d44ec2d409b04ab05d964bd5a403 introduced an incompatibility with Internet Explorer 11. On all merge requests in all projects the 'Changes' tab does not display the changes in IE11 but instead fails with 'Something went wrong on our end'. The reason ist, that this code snipped produces different results on Firefox and Internet Explorer 11:
```
var element = document.createElement('a');
element.href = '/some/absolute/url';
alert(element.pathname);
```
With Internet Explorer 11 the alert will print a relative path, whereas with Firefox the alert will print an absolute path. For GitLab this meant that a wrong AJAX URL was composed which resulted in a 404.
## Screenshots (if relevant)
None.
