Describe the bug

The "select all" button doesn't work as expected when there are filters applied

To Reproduce Steps to reproduce the behavior:

1. Search through a plugin and list some chapters
2. Apply some filters to reduce the number of chapters in the table
3. Click "Select all"
4. Click "Download selected". Notice that the confirmation box says "Download x selected chapters", where x is larger than the number of chapters in the table

Expected behavior

The number of chapters selected with the "Select all" button should match the number of chapters in the table
