Weird bug with DC template spawning

Hi all!

Here is Weird bug  with DC template spawning i am struggling to solve.

I do my development in Adobe Pro XI.

Recently i got complaints from users saying  template spawning would not work in Adobe DC.

I installed Adobe DC reader and found this weird bug

I created simple PDF to illustrate it.

1. PDF has hidden template named "RawDataPage"
2. PDF has 6 pages initially
3. First page contains 4 buttons.
4. Button 1  adds 1 template  after page 6, Button 2  adds 2 templates  after page 6 and so on
5. Close PDF without saving after button click, just observe spawning
6. You can find PDF files and screenshots at dropbox link https://www.dropbox.com/sh/qap5j5tzyomrlxw/AABGFv6Z0jGKE62SO6pgy2YSa?dl=0
7. I am going to update shared  folder upon information arrival
8. find all js code below inline

//<AcroForm>
//<ACRO_source>ButtonApply1:Annot1:MouseUp:Action1</ACRO_source>
//<ACRO_script>
/*********** belongs to: AcroForm:ButtonApply1:Annot1:MouseUp:Action1 ***********/
     getTemplate("RawDataPage").spawn(6, false, false);


//</ACRO_script>
//</AcroForm>


//<AcroForm>
//<ACRO_source>ButtonApply2:Annot1:MouseUp:Action1</ACRO_source>
//<ACRO_script>
/*********** belongs to: AcroForm:ButtonApply2:Annot1:MouseUp:Action1 ***********/
     getTemplate("RawDataPage").spawn(6, false, false);
     getTemplate("RawDataPage").spawn(6, false, false);


//</ACRO_script>
//</AcroForm>


//<AcroForm>
//<ACRO_source>ButtonApply3:Annot1:MouseUp:Action1</ACRO_source>
//<ACRO_script>
/*********** belongs to: AcroForm:ButtonApply3:Annot1:MouseUp:Action1 ***********/
     getTemplate("RawDataPage").spawn(6, false, false);
     getTemplate("RawDataPage").spawn(6, false, false);
     getTemplate("RawDataPage").spawn(6, false, false);
//</ACRO_script>
//</AcroForm>


//<AcroForm>
//<ACRO_source>ButtonApply4:Annot1:MouseUp:Action1</ACRO_source>
//<ACRO_script>
/*********** belongs to: AcroForm:ButtonApply4:Annot1:MouseUp:Action1 ***********/
     getTemplate("RawDataPage").spawn(6, false, false);
     getTemplate("RawDataPage").spawn(6, false, false);
     getTemplate("RawDataPage").spawn(6, false, false);
     getTemplate("RawDataPage").spawn(6, false, false);
//</ACRO_script>
//</AcroForm>

I expect code to be working in the same way both in Adobe XI and DC

See versions below

VERSION XI - 11.0.13	VERSION DC 15.010.20056

Now compare results

Button 1 ->ADDED 1  OK in both Acrobates

Button 2 ->ADDED 2  OK in both Acrobates

ADOBE PRO XI	ADOBE READER DC
Button3 - > ADDED 3 - OK	Button3->ADDED 3 - page 8 is broken
Button4->ADDED 4 - OK	Button4->ADDED 4 - pages 8,9  BROKEN

MORE WEIRD STUFF

1. SAVE PDF WITH  ADDED 4 PAGES FROM READER
2. OPEN IN ADOBE XI
3. SCROLL TO PAGE 7
4. Error reading (14)
5. Zoom jumps to 5983%
