Is the auto-merge broken text blocks capability active in the last stable version (3.0.5)?

[Alb93]

I'm experiencing some broken text blocks problems with the latest version of the library.

The pdf looks like this

and this is what I'm getting, as an example:
{ "x": 13.214, "y": 5.237, "w": 2.542, "oc": "#00416e", "sw": 0.44271875, "A": "left", "R": [ { "T": "QUA", "S": -1, "TS": [ 0, 13.72, 1, 0 ] } ] }, { "x": 14.743, "y": 5.237, "w": 4.115, "oc": "#00416e", "sw": 0.44271875, "A": "left", "R": [ { "T": "DRO%20RS", "S": 9, "TS": [ 0, 12, 1, 0 ] } ] },

Is there any way to activate the auto-merging step by using the library on a node environment? Is there any way to eventually tune it? Thank you!
