Indent inside filter tag indents the line after the endfilter when trimBlocks is true

[viennem]

When trimBlocks is true, and I use the indent filter inside a filter tag, like this:

{% filter indent(4, true) %}
myLine1
myLine2
{% endfilter %}
myLine3

then the line after the endfilter tag is also indented, and I get this output:

    myLine1
    myLine2
    myLine3

I was expecting this output instead:

    myLine1
    myLine2
myLine3

I am using nunjucks 3.2.4.

Workarounds:

1. Change the template like this:

   {% filter indent(4, true) %}
   myLine1
   myLine2
   {%- endfilter %}
   
   myLine3

2. Or set trimBlocks to false.

I confirmed that I get the expected output when using jinja instead of nunjucks.
