File containing equations

The file attached to this bug was exported by microsoft word and the equations inside it do not display correctly in LibreOffice Writer.

They display with black question marks instead of some characters.

screenshot in Windows with Writer 5.3.2 - OK

Equations that were wrong are MathType 5.0 and those that were fine are Microsoft Equation 3.0. MathType 5.0 can't be edited, that's Bug 33590.
Not reproduced in Windows. Looks OK with 5.3.2. Screenshot attached.

Reproduced as reported in Linux with 5.1.6 but better with 5.3.0 and master, just braces are missing. 
So I'll confirm but also change title.

On pc Debian x86-64 with master sources updated today or with LO Debian package 6.4.5, I don't reproduce this. (at least, I have braces at the locations indicated by screenshots).
Timur/Ophir: could you give a new try with 6.4.5?

I retested in Linux, looks wrong with 6.2+ and OK with master 7.1+.
In older LO I turned off Text Boundaries for braces to be seen better. 
I close as WFM, thanks Julien.

Seems also good with 6.2.8 so probably backported to 6.2, reverse bibisect could work with 6.2 or 6.3, and "rebisect" is always nice to pinpoint who fixed it.

Just a bonus, essential is the bug is fixed.
