Whitespace when generating custom form layout - video to show the problem

Description of problem:
When using custom form layout and its feature 'Generate template based on ...' the HTML template is generated, but it has so many whitespaces between elements, so that at first look it seems that nothing was generated.

See video attached for steps to reproduce and to see what I mean.

Version-Release number of selected component (if applicable):


How reproducible:
Always

Steps to Reproduce:
1. In group/repo/project demo > jbpm-playground > Evaluation open form evaluation-taskform
2. in Form Modeler go to form properties, select custom form layout and click Edit.
3. In 'Generate template based on' choose Default (but the problem is there also for the other options) and click OK next to it.
4. Examine the window displaying layout's HTML elements.

Actual results:
It seems there is nothing new generated there, but on closer look you can notice, that scrollbar appeared. This is because the form template with fields and labels IS generated, but there is so much whitespace between each element, that a lot of scrolling is needed.

Expected results:
No empty lines should be present between elements in the generated markup (also when using the other options 'aligned fields' and 'not aligned'). In ideal case the only whitespace that should be present should be formatting whitespace (e.g. the generated markup would be generated as if using for example http://xmlprettyprint.com)


Additional info:
With all the whitespaces a lot of scrolling is needed which makes it very hard to orient yourself in the markup.
