Search header does not allow of links in drop down
## Summary
From a pipeline result page, I cannot interact with the search header for longer search strings
## Steps to reproduce
_Note: I am using FireFox and have the GitLab preferences layout set to Fixed_
1. Navigate to: https://gitlab.com/gitlab-org/gitlab/-/jobs/3977924603
1. Enter this search term in the search nav: ` ee/spec/lib/gitlab/elastic/indexer_spec.rb`
1. Try to click any of the autocomplete items for where to search (gitlab project, gitlab-org group, or all gitlab)
## What is the current *bug* behavior?
you cannot click (or right click) any of those items
## What is the expected *correct* behavior?
You can click any of the where the search links and perform a search
