Fix page refreshes when filling in forms in Edge

Steps to reproduce:

Scenario 1

• Click on the Search button in the left menu.
• Click in the Collections field in the Search form.
  => At first, nothing happens (cursor doesn't appear in field), then the page refreshed.

Scenario 2

• Log in as a poweruser.
• Click on the Administration button from the left menu.
• Click on Users & Groups from the Administration menu.
• Click on the New button, then on User.
  => Page refreshes.

Scenario 3

• Navigate to a document.
• Click on the Start Process document action.
• Click on the dropdown menu to select a process.
  => Page refreshes.

Seems to be random: if the steps above are repeated without clearing cache and local storage, it is possible to fill in the form.
