%dl kills %th

When using %dl with short interval in a window, %th bubble does not show up.

I don't think that this is a bug. It is just one timing callback interfering with another.

You could experiment using %th[delay] and/or %th[ms_style] (assuming that you need to have a short time on %dl).

I agree that it is no bug. A hint in the documentation would be nice.
