I tested this PR, but long logs are still not readable (report page cannot be stretched).
And it added unexpected vertical space between the first lines.

Instead, in the same function, I tried to activate horizontal scroll bar :

scroll_area.setHorizontalScrollBarPolicy(QtCore.Qt.ScrollBarAsNeeded)

While it allows to see very long lines, it kills word wrap for the rest of the page.
So, moderately long lines cannot be seen at first glance anymore (because word wrap is dead), you now need to use the scroll bar for a lot of lines, which is far from ideal.

Thanks !
The WrapAtWordBoundaryOrAnywhere works, now everything is wraped.

But there is a catch : now, all the \n are ignored, so the nice readable layout is gone :

I found a solution to still use line returns : I replace \n by <br/>
