Mischievous Chips

😈🍟
Pasted outstanding issues from below:
- [ ] duplicate search term after pressing `:` ([here](https://github.com/guardian/grid/issues/1801#issuecomment-211126306))
- [ ] embarrassingly reveal the lack of UI responsiveness when cut long enough ([here](https://github.com/guardian/grid/issues/1801#issuecomment-203310481))
- [ ] pressing `-` should not immediately launch a chip preventing one from running NOT queries! ([here](https://github.com/guardian/grid/issues/1801#issuecomment-415416068))
- [ ] collections should be suggested ([here](https://github.com/guardian/grid/issues/1801#issuecomment-206925687))
- [ ] keyboard navigation between free-text and chips is broken (left, right, tab/shift+tab)
- [ ] suggestions shouldn’t be scrollable where there is space and navigating them by arrow keys should scroll them
- [ ] chips don’t work with [arbitrary fields](https://github.com/guardian/grid/pull/3132), eg. `+"fileMetadata.colourModelInformation.hasAlpha":"true"`
- [ ] chips, when committed, end up at the beginning of the search box, ie. try typing `cats +fileType:png`. This reordering does not affect URL. But it will create problems when order of the search arguments will matter (eg. for `OR` searches)

~~~
- [x] Cannot click into search box in embedded Grid on FF.
- [x] Cannot select text.
- [x] Double-clicking to select all doesn't work if you do it in the are after the word.
- [x] When try to select text with a broad click-drag, depending on where do you start dragging (still: always within the text box area), different glitches happen in different browsers...
- [x] Cannot Paste (from the context menu).
- [x] Struggling to insert my cursor into the search field or to highlight the words in order to edit them.

Review the unchecked behaviors in this issue, especially chip creation, keyboard navigation, suggestions, arbitrary fields, and argument ordering. Reproduce the listed search-box interactions and determine which outstanding behavior remains; done means the selected behavior works without regressing the completed cases.
