Expected Behavior

n/a

Observed Behavior

n/a

This is not a reproducible bug. However in 4 different HTML files, there are some {% tag %} tags with incorrect spacing. While functional, they do not conform to the existing standards for all other tags.

For example, {% tag %} can be found written as either {%tag %} or {% tag%} in some places.

The UI is currently being overhauled for v2.11 under #5893. We're not doing any maintenance on the current templates until that initiative has been completed.
