The find functionality is currently not available for small devices
because the find dialog is not responsive. This patch fixes that.
To achieve this goal, the HTML is changed to always show the find
button. To prevent issues because of the addition of an extra button for
small views, the previous/next page buttons are hidden if the view
becomes small. These buttons are not useful anyway because on small
devices navigation is usually done via scrolling. The find functionality
is much more useful to have in this case. Moreover, we wrap the existing
elements into separate `div`s so that the browser can position the
elements itself when the view becomes smaller and logically connected
elements stay together when this happens.
In the CSS, extra rules for the find bar have been added to ensure that
the dialog's doorhanger is always below the find button. All findbar
`div`s are forced to be 32 pixels high to prevent the find message text
being aligned under the checkboxes. Finally, the find message is only
visible when there is actually text to display. This prevents wrapping
issues because, by default, the label has padding and margin even if
there is no text.
