Class attribute cannot be removed via the |attr filter

[rungta]

Description

This example from the docs for |attr does not appear to be working in Craft 3.5:

{% set tag = '<div class="foo">' %}
{{ tag|attr({class: false})|attr({class: 'bar'}) }}
{# Output: <div class="bar"> #}

Actual output: <div class="foo bar">

Additional info

• Craft version: 3.5.16
• PHP version: 7.1

Thanks for pointing that out! Just fixed this for the next release.
