Missing x- and y-ticks at 0.0 with `set_zero_subnormals(true)`

[thchr]

A Python package I'm loading (via PythonCall) is somehow setting set_zero_subnormals(true). That's annoying, but I wasn't aware - but what made me aware was that this affected my plotting in Makie.

Specifically, it makes it so that x- or y-ticks marks set to 0 are not shown:

julia> set_zero_subnormals(true);

julia> using GLMakie

julia> faxp=plot(0.0:1.0:5.0, rand(6))

julia> faxp.axis.limits = (0.0, 5.0, 0.0, 1.0)
(0.0, 5.0, 0.0, 1.0)

Will result in a plot like this (not the missing x- and y-tick marks at zero):

The tickmarks do not appear even if we set x.ticks = ([0.0, 5.0], ["Start", "End"]) (similarly for the y-ticks).

You could reasonably argue that the real issue is that pyimport in PythonCall sets set_zero_subnormals(true), but after discussion on Slack, I figured I'd file it as an issue anyway.
