Compatibility issue with Twig

[emulienfou]

Since the version 2.2 of this bundle, in the next template file Resources/views/Form/form_div_layout.html.twig you made a change from using the Twig tag spaceless to apply spaceless.

However, this new tag has been added from Twig versions 1.40, 2.9 and 3.0. But in your composer.json you didn't require a specific version for the package twig/twig.

So I had an example with an old project who are using Twig ~1.35.0 with Symfony 4.4 and since there is no requirement for Twig package, the version 2.2 of liip/imagine-bundle has been installed and generate an issue, because the tag apply in not existing in this Twig version.

I think you should specify a twig requirement version for the package twig/twig, such as:
"twig/twig": "^1.40|^2.9|^3.0".
