incorrect icon: Improve close / checkmark icon.

[infacto]

Describe the Issue

Just a minor but somewhat annoying issue from a meticulous UI dev. Especially when using close and checkmark icon together. It seems that either the close is not correct or checkmark. You can decide.

Comparison

Type	Close	Checkmark	Compare	Comment
outline				Seems ok.
filled				The close appears too thick or the checkmark too thin.
sharp				Seems ok.

We see that the checkmark outline and filled appear the same. The filled checkmark should be thicker or the cross thinner.
