Dedent removes space from block

[Gappa]

Version: 3.1.3

Bug Description

Space gets removed from a block inside a HTML class. Sure, not the prettiest code, but it works without dedent :)

Steps To Reproduce

Compile this code with Dedent enabled:

<div class="page-content{block page-content-class} content-area{/block}">
	Stuff
</div>

PHP result:

/** {block page-content-class} on line 63 */
public function blockPage_content_class(array $ʟ_args): void
{
	echo 'content-area'; // no space at the start of the string
}

HTML result:

<div class="page-contentcontent-area">
	Stuff
</div>

Expected Behavior

Without Dedent:

/** {block page-content-class} on line 63 */
public function blockPage_content_class(array $ʟ_args): void
{
	echo ' content-area'; // space at the start of the string
}

<div class="page-content content-area">
	Stuff
</div>
