I found a bug when using the Pager component (<ejs-pager>), the page sizes dropdown is not consistent. These are the steps to reproduce it (which are shown in the video attached as well)
1. Refresh the localhost page.
2. In the code change the page-sizes prop from Array to Boolean true (or vice versa)
3. Then go to the browser (do not refresh) and you should see the dropdown.
4. Then refresh the page and it disappears
5. Reproduce again steps 2 to 4, to confirm the same behavior.
