CSV Export using current fields does not follow the visible column configuration

Issue

When exporting issues from the issue search page, the option Export > CSV (current fields) does not respect the columns selected in Columns > Filter. Instead, it uses the columns selected in Columns > My Default.

Steps to replicate

1. Go to the issue search page and enter a search query
2. Configure the setting Columns > My Default to only show 2 columns (For example: Assignee and Created)
   
3. Switch the column configuration from Columns > My Default to Columns > Filter, and add a few extra columns such as Sprint, Component and Summary
   
4. Export the search results using the option Export > CSV (current fields)
5. Open the CSV file

Expected behavior

The CSV file should contain the 5 columns selected in Columns > Filter (Assignee, Created, Sprint, Component and Summary).

Actual behavior

The CSV file only contains the 2 columns selected in Columns > My Default (Assignee, Created)

Workaround

Before exporting issues as a CSV file, select the columns you want to export in Columns > My Default instead of Columns > Filter
