`display: flex` doesn't play well with Notifications Beta search #2703

Without the extension enabled:

With the extension enabled (quick search overlaps the search box):

I looked at the CSS used by refined-github, and it changes the display of the search elements from block and inline-block to flex. The autocomplete is a block and ends up interacting poorly with other elements there.

I'm using this custom CSS as a workaround:

.js-notifications-container .subnav-search-input {
    display: inline-block;
}

.js-notifications-container .subnav-search {
    display: block;
}

but there's probably a better way to do it (using flex for the autocomplete, for example).
