custom product attributes without spaces on PDF

Hi there,

With the latest fix, attributes are shown on the pdf-download as well as on the print. What is a bit annoying though is that any spaces contained in attributes are trimmed. For instance, a custom attribute of a variable product like “without runtime license” is shown as “withoutruntimelicense” – not exactly easy to read.
Note that this bug seems to be limited to custom product attributes (see attachement: green for global attribute, red for custom product attribute).

We use the AJAX template of version /** 2.2.2 – 2022.. **/

cheers,
Rudolf
