Issue Summary

Exporting a space with XML results in the UI showing 20% for a very long time with a space that has 6kb but on the backend is showing 100%.

Steps to Reproduce

1. Navigate to a space
2. Perform a full export in XML
3. The export status will show 20% Complete: Creating the zip file but will remain stuck without updating the page for a long period

Expected Results

The export would finish and display 

Actual Results

The export status remains stuck at 20% for an extended period but on the backend, the status is complete at 100%

Inspecting the network will continually return:

GET https://eptura.atlassian.net/wiki/rest/internals/1.0/io/export/spe-ID
Status Code: 200

Response:
{
 complete: falsee
 lapsedTime: 2306
 id: "spe-ID"
 message: "Creating the zip file"
 percentage
 Complete: 20
 result: "/wiki/download/temp/filestore/null"
 successful: false
}

Workaround

Currently, there is no known workaround for this behavior. A workaround will be added here when available

Contact support to review the ID, if the page does not refresh after a period of time.
