Inside a book, Ctrl+F search keyboard shortcut does not work if the book pages are focused instead of the sidebar

[nekohayo]

To Reproduce
Steps to reproduce the behavior:

1. Enter a book
2. Click on the Search button
3. Press Esc to toggle off the search
4. Press Ctrl+F, notice the searchbar reappears
5. Press Esc to toggle off the search
6. Click the book's page contents on the right, so that the focus is no longer on the sidebar (even if the sidebar is pinned)
7. Press Ctrl+F to try to activate and focus (and select-all) the searchentry's contents

Expected behavior
Search entry gets reactivated, and existing query text (if any) should be all preselected (so that the user can replace/overwrite it, or choose to extend it instead)

See #1279 (comment)

Guess that means it was caused by a change in how WebKitGTK handles shortcuts.

At any rate, this should be fixed in v3.1.1.
