Admin global search - submit by enter doesn't work

[ihor-sviziev]

When I'm trying to submit search form from keyboard - it doesn't work, but if I just click to value in drop-down - it works as expected.

Preconditions

1. Magento 2.1.7 installed via composer

Steps to reproduce

1. Go to Magento 2 admin panel
2. Click "Search" icon in header
3. Put some query (as example 7029) in search field, wait for autocomplete
4. Select "<your query>" in Products option with arrow keys on keyboard
5. Click enter button
   

Expected result

1. Browser should be redirected to products grid page with selected query

Actual result

1. Browser was redirected to the current page with additional get parameter: ?query=#
