Is this okay to unset overflow in cm-gutter?

I tried to style gutters in editor so that they slightly overlap the content.

I achived this by setting: margin-right: -4px to .cm-gutterElement and setting overflow:visible to .cm-gutter.

Is this okay, or can this break something?

Frankly, I’m not sure, and I can’t give any guarantees on that.

@marijn I would like to achieve fold gutters similar to those in WebStorm. You can see they slightly overlap

Can this be done with code mirror safely?
