Reproduced the initial issue on an asan build from 71.0a1 20191001041624, the tab with the testcase crashes with : Assertion failure: mPresContext->GetVisibleArea().width != nscoord((1 << 30) - 1) (width should not be NS_UNCONSTRAINEDSIZE after reflow), at /builds/worker/workspace/build/src/layout/base/PresShell.cpp:1994 Proceeded onto verifying the testcase on on m-c-20191125042312-fuzzing-asan-opt: the tab doesn't crash anymore, no asserting failure, however, I get an NS_Error_failure on line 17 on tab.sizeToContent() -> XHR POST http://localhost:8000/1 [HTTP/1.0 501 Unsupported method ('POST') Wonder if this is expected, :emilio, could you please advise?
