Alternate surrogate/formatting template name syntax

[CrystalClearGal]

DynamicPageList3 version:
MediaWiki version: 1.39.4
PHP version: 8.1.27 (cgi-fcgi)
DPL3 version: 3.5.2

Issue:

• The manual's include section states the following alternate surrogate template naming syntax works:
  {ParamSourceTemplate¦AltNameSurrogate}.dpl
• However, it only works in debug=5 mode, outputting desired results as "pre"-escaped.
• In normal mode, even with debug=0 explicitly set, the result is "pre"-escaped for no reason.

List of steps to reproduce (step by step, including full links if applicable):

1. On Template:MyTemplate page, put:

{{#dpl:
|debug=0
|namespace=
|category=My Category
|include={ParamSourceTemplate¦AltNameSurrogate}.dpl
|mode = userformat
|listseparators = ¶{¦class="wikitable" 
¶¦-¶!Page ¶!Props ¶!colspan="2"¦Requirements¶¦-,,,¦}
|secseparators	    = ¶,,,¶¦,
|count=10
|noresultsfooter='''No results found'''
}}

2. Add a surrogate called Template:AltNameSurrogate with 3 cells calling 3 valid ParamSourceTemplate params.

3. Preview the Template:MyTemplate template page result.

What happens?:

• All output displays as "pre" tag escaped, even with explicit |debug=0.

What should have happened instead?:

• Content should display as intended.

Browser information, screenshots and other applicable information:

• Any browser (unrelated to browser).

Workaround:

• Redirect the "required"-syntax-named template's page, to the desired named one (or the namespace/page used as the desired surrogate). This functions as an alias of sorts.

Is there an example page where this happens? I couldn't seem to reproduce.

Good question. You beat me to making a live example for this one, so not yet. :)

I'll try to do one in the next day or so, as it was one of the more obscure functions I wanted see if it still works (or if it ever did--would be nice as having to name the same as the parent template is not always ideal).

Here's a much simplified example (the debug mode issue was resolved).
The remaining issue is alternative surrogate (or formatting) template naming, which otherwise must follow the data entry source template name.
