Yes.

Since I reported this some time has passed.
In the meanwhile I did dig the code and found out it actually is a feature.
It's made in purpose, but don't actually know why. 
So I'm not sure any more.

Hi Dante,

I guess this happens because the "=" sign is a binary operator that forces both sides to be together. This is why the "b = 5" appears at the top of the sum operator.

Indeed you're right. This is a "feature" of the language used by LO Math.

I don't know where you were trying to get at with "sum from a to b = 5 ff", but maybe you would need to enclose some portions of the formula using "{" and "}".

Something like this:
{sum from a to b {}} =  {5 ff}

I'll close this as NOTABUG for now. If you have a different opinion, please reopen it.
