In Docs, I cannot re-trigger search by search icon or enter key

What are the steps to reproduce your problem?

• enter search term in the docs search field and hit enter
• select a result
  --> you will be forwarded to the search result
• go back in the browser history
  --> the old search term is still in the search filed
• search again with the old search term

What is the problem?

• cannot trigger the search

What would be the expected behavior:

• by selecting the search icon or hitting enter the search should be triggered again
