2. Add Web Content Display to a page
3. Remove one of the first portlets from the page
4. Click to remove Web Content Display
5. When the dialog pops up, there will be a checkbox saying "Prevent this page from creating addition dialogs" > flag that and click OK
6. Remove another portlet from the page

The portlet is removed.

Actual result:
The portlet is not removed.

Note: Reproduced with Chrome. The steps are like LPS-60364, but it is not the same issue. This issue happens before LPS-60364 happen.
