Bookmarks are missing after splitting PDF files in Adobe Acrobat.

When splitting a PDF file in Adobe Acrobat -26.002.22031 using the "Split by File Size" option, the bookmarks are not properly retained in the resulting files. For example, if the original PDF contains 50 bookmarks and is split into two files, both output files retain only the first 9 bookmarks from the beginning of the document. The remaining bookmarks are missing, even though the corresponding pages exist in the split files.
