Gallery Pro - Lightbox Template problem

## Prerequisites

- [x] I have searched for similar issues in both open and closed tickets and cannot find a duplicate.
- [x] The issue still exists against the latest stable version of Elementor.

## Description
When there is more than one Gallery on a page, which is imported by a Template (because it's embedded in a Tab for example), then the Gallery skips through ALL photos of ALL Galleries on that page.
When multiple Galleries are on one page, normally the Lightbox just skips through the opened Gallery of that page and not through all the Photos of all Galleries.

## Steps to reproduce

Create a new page.
Add a Tab widget with 2 tabs.
Import the content of the Tabs via a Template which contains a Gallery.

## Isolating the problem

- [X] This bug happens with only Elementor plugin active (and Elementor Pro).
- [ ] This bug happens with a default WordPress theme active.
- [X] I can reproduce this bug consistently using the steps above.
