Javascript errors on Webprofiler settings page

Currently, when accessing the URL /admin/config/development/devel/webprofiler the following uncaught error happens.

drupal.js?v=8.3.2:59 Uncaught Error: Syntax error, unrecognized expression: :input[name="active_toolbar_items[database]

I did a little digging and it appears to be related to a malformed selector which results in Drupal behaviors code throwing the error.

Changing that line to the following code appears to resolve the issue. I no longer see JS errors and I can still toggle the database toolbar node correctly.

 'input[name="active_toolbar_items[database]"]' => array('checked' => TRUE),

I haven't worked with Drupal much at all (especially 8) and I'm not sure if there are any ramifications of my fix but it seems to work fine.

I'll see how I go about creating a pull request or where to send the patch to.
