[Interest] Any possible workaround for QTBUG-40889 ?

[Elvis Stansvik]

I'm in the unfortunate situation of having to support Qt 5.5.1, and
I'm hit hard by

    https://bugreports.qt.io/browse/QTBUG-40889

which was fixed in 5.6 with

    https://codereview.qt-project.org/#/c/126136/

Anyone know if there's any way to work around this bug with Qt 5.5.1?

It's so unfortunate that *buntu Xenial didn't make a freeze exception
to bring in 5.6 :(

Thanks in advance,
Elvis
