Wrong behavior when selecting all document in OpenOffice and LibreOffice

[jawhien]

If you open the document in OpenOffice or LibreOffice writer, press CTRL+A, NVDA reports or part of the selected text, or simply silent. If the document is small, NVDA correctly pronounces the selected text.

Steps to reproduce:

To access a sufficiently large document in OpenOffice or LibreOffice. writer Press CTRL+A to select the entire document.

Actual behavior:

NVDA says or part of the selected text, or silent.

Expected behavior:

Should correct to speak selected text, or the number of allocated symbols, as it happens in Microsoft word.

System configuration:

hi. i confirm this problem in libreoffice and openoffice and any version of nvda which i tested, the issue is the same. but its the behaviour of nvda in general when selecting large text. for example: if i select more than 1024 characters in web browsers or notepad++ or any other programs and press control+a to select entire document, immediately after pressing control+a, or when using nvda+c to read clipboard, nvda says: the clipboard contains a large portion of text. its 1900 characters long. for example. is there any solution that nvda reads entire text when i selected all of its content without any limitation of characters number? i appreciate any of help, God bless you!

This appears to be caused by the same underlying issue as #4115, #4119.

This likely has the same root cause as described in https://bugs.documentfoundation.org/show_bug.cgi?id=91739 and https://bugs.documentfoundation.org/show_bug.cgi?id=35652 (LibreOffice Writer currently doesn't expose off-screen paragraphs on the a11y level.)
