No icon for add-on in side pane

since Komodo Edit 10 I noticed that there is no icon on the label of the side panel in which there is an add-on.
In the image below I’m using Komodo Edit 11 (fresh installation) with two add-ons but for both of them no icon on the relative label is shown.

Is this normal or is an issue (whose is it? Komodo or add-on?).
If this is how it is supposed to be, is there any way to add an image to the label?


That is an issue that should be resolved by the addon developer, please report it to them.
