958914 - Scriptlevel doesn't change when moving child in reftest

Status: RESOLVED DUPLICATE of bug 838506

(Core :: MathML, defect)

Description

[James Kitchener (:jkitch)]

Attachment: reftest

In movechild.html (in the attached reftest), an <mo> element is moved from within an <mfrac> to a separate <math> element with no scriptlevel increasing elements.

When run without the "MozReftestInvalidate" event listener (ie adding a direct call to doTest()) the element is moved and its scriptlevel is changed from 1 to 0, which is the expected behaviour.

When run as part of a reftest using "MozReftestInvalidate" event listener, the element is moved but its scriptlevel remains at 1.

Is there something wrong with my testcase, or is there an underlying bug that only manifests itself with reftests?

This reftest passes for me with the refactoring of displaystyle (that includes change to displaystyle / scriptlevel computation in mfrac). See bug 838506. I have not tried to run the reftest without that refactoring.

I've run the patches from bug 838506 and they appear to fix the problem.

A testcase to ensure it stays fixed will be included in bug 442637.
