Freemarker compresses single_line without spaces

It seems that <@compress single_line = true> replaces line breaks with single spaces ("") instead of just suppressing them.

Example:

<@compress single_line=true>
"First cell"
<#if something >
    |"Second cell"
</#if>
|"Third cell"
</@compress>

Print:

"First cell" |"Second cell" |"Third cell"

It is not possible to analyze an outdated system just because of gaps between the pipes.

Is there a way to avoid this ?, perhaps a way to read every “nested” line in a macro to replace @compress functionality?

In the end, I do not need “structural source code”, but the view code, so assigning variables just to print the result will not be pleasant.

Thank you in advance, kindly.

The following solution also works fine:

<#assign var>
"First cell"
<#if something >
    |"Second cell"
</#if>
|"Third cell"
</#assign>
${var?replace("^\\s+|\\s+$|\\n|\\r", "", "rm")}
