Steps to reproduce

1. Upload a svg file
2. Run this template:

{% set icon = craft.assets.filename('CloudArrowUp.svg').one %}
{% if icon %}
    {% dd svg(icon) %}
{% endif %}

Fun fact and workaround for now:

If you call the url method before the svg function, it works:

{% set icon = craft.assets.filename('CloudArrowUp.svg').one %}
{% if icon %}
    {% do icon.url %}
    {% dd svg(icon) %}
{% endif %}

Expected behavior

Svg content is output

Actual behavior

An empty string is return, an error is logged
