Investigate loading of JS/CSS assets

[manuelaugustin]

Context: Why was this issue created?

We currently load some JS/CSS assets on the editor even when the functionality associated with it is disabled. We should investigate what we can optimize here so that we're sure only to load the necessary assets.

What is the goal of this issue?

What needs to be done to achieve the goal?

Does the issue still need UX or research?

If available: what are the tips for fixing the problem or possible solutions?

What is the expected result/behavior?

Should documentation be added or updated for this change? and if so, where?
