How is Path of Building expected to behave?

When exporting a build with "Export support" checkbox checked, it will just export the build itself. The exported build will not be affected by any PoB config like boss preset, delirious effect, enemy boss config etc.

How does Path of Building behave?

When exporting a build with "Export support" checkbox checked, the build will be exported with the uber pinnable boss modifier "70% less damage taken" included (if that option is selected in the config), unexpectedly adding a multiplicative 70% less damage modifier to any other build.

How to reproduce the issue

1. Create any build, even an empty build works.
2. In the Enemy stats section, set the Is the enemy a Boss? dropdown to Uber Pinnable Boss.
3. Export the build with the Export Support checkbox checked, and import it to any other build.
4. Watch dps drop by 70%.

Start at the Export Support checkbox flow and the Enemy stats/Uber Pinnable Boss configuration, then trace the export and import entry points. Reproduce the issue with an empty build and verify that importing an Export Support build no longer carries the selected boss modifier or its 70% less damage effect.
