Size of branch labels

Hi,

terrific library you made here! I just have one question regarding styling - I cannot find a way to increase the size of the branch labels. The default is absolutely tiny and seems to shrink when I zoom in too. Since I am using this to visualize epidemiological data, the branch lengths are kind of a big deal for interpretation (i.e. distance between isolates).

Is there any parameter to control this? Couldn't find anything in the documentation, sadly. I think the non-gl version of Phylocanvas exposes more config options, but I need something I can just embed in HTML...

Kind regards, Marc
