> 2064 [NNNNN] WARNING: NS_ENSURE_TRUE(newRoot) failed: file dom/base/nsRange.cpp, line 1132

This warning [1] shows up in the following test suites:

> mozilla-central_ubuntu64_vm-debug_test-mochitest-e10s-2-bm53-tests1-linux64-build12.txt:2051
> mozilla-central_ubuntu64_vm-debug_test-mochitest-2-bm67-tests1-linux64-build1.txt:2051

It shows up in 8 tests. A few of the most prevalent:

> 1554 - dom/imptests/html/dom/ranges/test_Range-set.html
> 1554 - dom/imptests/html/dom/ranges/test_Range-set.html
> 261 - dom/imptests/editing/selecttest/test_extend.html
> 261 - dom/imptests/editing/selecttest/test_extend.html
> 177 - dom/imptests/editing/selecttest/test_collapse.html
> 177 - dom/imptests/editing/selecttest/test_collapse.html
> 59 - dom/imptests/editing/selecttest/test_selectAllChildren.html

Actually this is limited to 2 tests (4 if we count both non-e10s and e10s). The generic warning shows up further, but the one from line 1132 is limited to:

> 777 - dom/imptests/html/dom/ranges/test_Range-set.html
> 777 - dom/imptests/html/dom/ranges/test_Range-set.html
> 255 - dom/imptests/editing/selecttest/test_extend.html
> 255 - dom/imptests/editing/selecttest/test_extend.html

AFAICT test_Range-set.html [1] and [2] test_extend.html intentionally trigger the warning and down the line we throw an appropriate exception (INVALID_NODE_TYPE_ERR). It seems like the warning is unnecessary.

Olli, would you mind reviewing this or redirecting to a more appropriate reviewer?

Remove warning if invalid node type is passed to nsRange::SetStart

yeah, this should be per spec, so expected.
