Issue Summary

When I create a table and then insert JIRA Issue/Filter items into each cell. I've put my cursor in the empty cell and then insert it, and instead of populating the cell I had selected, it adds the JIRA item into the previous cell. 

Steps to Reproduce

1. Create an application link between Confluence and Jira.
2. Create a project in Jira and add issues.
3. Create a page on confluence.
4. Add a table.
5. Select a cell of the table and insert a JIRA Issue/Filter macro.
6. Execute step 5 again, however, selecting a different cell.

Expected Results

Since I have selected a new cell, the JIRA Issue/Filter macro must be populated on the newly selected cell.

Actual Results

After selecting a new cell to populate the result, it adds the JIRA item into the previous cell and not on the new cell.

Workaround

Drag and drop the Jira items to the desired cell.
