Bug: Boolean Title Attribute

I recoginized that my boolean attributes is always false, when I add a title to it. Can somebody confirm this? When I remove the title it works as expected.

DrawUSPContainer.attributes.add('is3Dusp', {type: 'boolean', title: "3D USP"});

Seems to work fine for me?


I always add titles to attributes and I haven’t had a similar problem.
