IE10 LayoutContainer test failures

[haysmark]

It seems nothing is appearing in the list of tab-able elements?

 GROUP "LayoutContainer" has 2 tests to run

Thanks, I'll check in a fix. Since it's only changes to test I guess it doesn't need to be backported.

[bill]

In [29790]:

Restrict walkTree() workaround code to IE8 or less, since it actually makes things worse on IE10. Also ignore IE10 rounding errors. Fixes #16130.

[haysmark]

Also happens in 1.7. Would like to see [29790] backported to fix these LayoutContainer? errors.

[bill]

In [29947]:

backport [29790] to 1.8 branch, refs #16130

[bill]

In [29948]:

backport [29790] to 1.7 branch, refs #16130

[bill]

Marking as task since it was only a test issue.

[bill]

In [30243]:

backport IE10 test fix [29790] to 1.6 branch, refs #16122, #16130 !strict.
