rowSpan creates big row heights if it spans across a page

[JoachimSoftpauer]

I am using rowSpan but when I have a big table and its spans multiple pages, sometimes the last row of the span extends to a much bigger height than what I specified on the table.

Here is a snipped you can put in the playground:

// playground requires you to assign document definition to a variable called dd
var dd = {
  "content": [
    {
      "table": {
        "headerRows": 0,
        "dontBreakRows": true,
        "keepWithHeaderRows": 1,
        "heights": 45,
        "widths": [50, 100, 200, 50],
        "body": [
          ["1", "2", "3", "4"],
          [{
              "rowSpan": 4,
              "text": "4spamn"
            }, null, null, null],
          [null, null, null, null],
           [{
            "rowSpan": 2,
            "text": "2span"
          }, null, null, null],
          [null, null, null, null],
        [{
            "rowSpan": 2,
            "text": null
          }, null, null, null],
          [null, null, null, null],
           [{
            "rowSpan": 2,
            "text": null
          }, null, null, null],
          [null, null, null, null],
           [{
            "rowSpan": 1,
            "text": null
          }, null, null, null], [{
            "rowSpan": 15,
            "text": "span 15",
            "maxHeight": 50,
          }, null, null, null],
          [null, null, null, null],
          [null, null, null, null],
          [null, null, null, null],
          [null, null, null, null],
          [null, null, null, null],
          [null, null, null, null],
          [null, null, null, null],
          [null, null, null, null],
          [null, null, null, null],
          [null, null, null, null],
          [null, null, null, null],
          [null, null, null, null],
          [null, null, null, null],
           [{
            "rowSpan": 1,
            "text": null
          }, null, null, null],
           [{
            "rowSpan": 1,
            "text": null
          }, null, null, null], [{
            "rowSpan": 1,
            "text": null
          }, null, null, null],
          [{
            "rowSpan": 5,
            "text": "span 5"
          }, null, null, null],
          [null, null, null, null],
          [{
            "rowSpan": 2,
            "text": null
          }, null, null, null],
          [null, null, null, null],
          [null, null, null, null]
       ]
      }
    }
  ]
}

In the example the span 5 has a massive final row

and if I change the heights to say 30

the span 15 does a similar thing

but if I change the heights to 47 span 15 no longer breaks and all rows are the correct height even though the span stretches over multiple pages.

Does anyone know of any rules that PDF make is applying that explains why this happens or is it a bug?
