Hi devs,

I found different results when I want to dissolve line vector layer by
attribute value :

With Dissolve processing alg,  features are merged but with Multilinestring
geometry type for dissolved cases, and Linestring geometry  for other cases.

With group by action from vector menu, all  features get Linestring type.

Is ‘group by’ behavior the right one? In such case should be  Dissolve
processing alg improved?

Which QGIS version? I think this was recently fixed in master.
