Javascript sourcemaps and Breakpoints no longer work in Chrome 43

I am using Chrome 43.0.2357.81 (64-bit) and Jetbrains plugin 2.0.8. and Rubymine 7.1.2

It appears that RubyMine is no longer downloading or processing sourcemaps for debugging. I am basing that on the fact that when debugging, the "Scripts" tab no longer shows me any files referenced by sourcemaps, but instead only shows me JS files. If I try to set a breakpoint in the source TS files, the red circle never gets the checkmark showing that it's actually been set. Chrome itself is respecting and using the sourcemaps, because I can set breakpoints in the Typescript source code and debug in the Chrome debugger without issue.

Is there another way for me to debug this, investigate further, or force Rubymine to begin downloading/loading my sourcemaps again?
