- Use checkbox-select-all’s form attribute if it exists and the closest form only if it doesn’t. Make sure to update checked state of any other select-all checkbox when one changes state.

- Use form="id" attribute to simplify form markup
- Includes polyfill for legacy browsers

* Reduce to one search bar.

- Use jQuery to handle data attributes (needed for IE 9/10).
- Fix issue with all IE versions where Recaptcha dialogs don't accept any button presses.

- eslint issues
- hidden checkboxes were not toggling correctly, so functionality was broken

- Load Google library once per page, instead of once per Captcha
- Allows proper functioning of multiple embedded ReCaptchas in a single set of search results

- Resolves VUFIND-1197

After exploring new options to make login detection more robust, this is still the best system. Will continue to investigate.
