Question: Option to add padding between {{ and }} for Jinja / Twig?

I've tested online version for jinja and twig and i see it auto add space between {{ and }} for variables. What's the option to it?

I think I am automatically adding the space without any option from the parser. Is the space cause a defect or is there a scenario when the code would be better without the spaces?

The default behaviour on other IDE/editor is to add spaces between {{ }} and {% %}
