Is this still broken in 10.3.1?

Q: LogPlot axes labels destroyed when working in high precision

Bug introduced in 7.0 or earlier and persisting through 10.2.0 or later (I'm using Mathematica 8.) I have a Taylor series: poly = Normal[Series[E^x, {x, 0, 10}]] I want to produce a log-linear plot of the error. This is easy enough with the following code: LogPlot[Abs[E^x - poly], {x, -1,...
