Document Task Board Corner & Flag/Released field visibility

The Task Board in List view has some design characteristics to optimise the issue when space is limited.
Depending on the combination of browser size and column count the corner-field and/or the issue flag/issue released will be hidden. This is done when the issue is too small to allow them to be shown and the issue key and issue summary to be legible and the issue summary to be editable.

This is from version 5.0 onwards, before this the List issue view did not allow inline-editing.

To view the fields if they are hidden solutions would be:
1. Make the browser window wider if possible
2. Hide one or more columns, using the cog actions in the column, until the fields become visible.
