TextField's stretch property doesn't work when generating a report

[competense]

I am using phpjasperxml in Laravel 11 and a jrxml file from Jaspersoft Studio 6.18. Things work as expected except for the stretching ability of a TextField. I need it to stretch as some of the string values for a database field are more than one line (i.e. 1-1000 characters).

I have tried many combinations in the properties, but I think it always has something to do with Position Type= Float, Stretch Type = <anything except "No stretch">, and Text Adjust = StretchHeight.

The preview of the jrxml file is working as it should, but the PDF file generated from the same jrxml file isn't.
