Issue Summary

When using the any gadget in Dashboard, it is not recommended to use a saved filter that uses purely issue keys as its JQL because if there are too many issue keys in the query then the request will be too large and cause it to break.

Steps to Reproduce

1. Create a saved filter using only issue keys ("key in (PKEY-1, PKEY-2, PKEY-3, PKEY-4)"). This was tested with 600 issue keys and above.
2. As an example, add the Two Dimensional Filter Statistics gadget to your Dashboard and use that saved filter you've just created
3. Click on the highlighted number count to view the results of the XAxis or YAxis field selected.

Expected Results

You will be redirected to a new tab displaying the results based on the XAxis or YAxis field used.

Actual Results

414 Request-URI Too Large

Workaround

The saved filter must be adjusted to use field references for its JQL and not purely use issue keys.
