Description:

To reproduce issue:

1. Create new dashboard with no widgets.
2. When the dashboard loads it will show a modal saying to add a widget or set to default layout. Click "Add a widget".
3. This should expand the dashboard manager, but does not currently.

Cause is due to ExpandOnClick using a native event handler on a link then trying to use jquery.trigger('click') to trigger the handler. jQuery sometimes ignores native event handlers, but not always, and it is complex to make it work in every case.

Also added some environment variables to the build vue polyfill command.

Review

• Functional review done
• Potential edge cases thought about (behavior of the code with strange input, with strange internal state or possible interactions with other Matomo subsystems)
• Usability review done (is anything maybe unclear or think about anything that would cause people to reach out to support)
• Security review done
• Wording review done
• Code review done
• Tests were added if useful/possible
• Reviewed for breaking changes
• Developer changelog updated if needed
• Documentation added if needed
• Existing documentation updated if needed
