Note that content scripts must have non-default execution context.

[lushnikov, 2017/03/16 06:30:49]

Done.

[dgozman, 2017/03/16 00:17:10]

this._executionContext.auxData

[lushnikov, 2017/03/16 06:30:50]

Done.

Let's call lineEndings on it and pass true endLine/endColumn?

[lushnikov, 2017/03/16 06:30:49]

Done.

[dgozman, 2017/03/16 00:17:09]

I believe this one is not required.

[lushnikov, 2017/03/16 06:30:49]

We currently send it whenever the page gets reloaded

[dgozman, 2017/03/16 00:17:09]

Should we list all scripts here?

[lushnikov, 2017/03/16 06:30:49]

I consider those to be evals for simplicity; renamed the method to make this
clear
