Word document reproducing the bug

When extracting the text of a Word 97 document I get the following INFO in the logs (using poi-scratchpad 5.2.3): 

2023-02-06 10:15:08,983 INFO  [org.apa.poi.hwp.spr.SectionSprmUncompressor] (executor-thread-0) Unsupported Sprm operation: 58 (0x3A)


The following unit test reproduces the issue (using the attached .doc file): 

    @Test
    void testSprmOperation58() throws IOException {
        try (HWPFDocument hwpfDocument = openSampleFile( "hello_poi.doc" )) {
            WordExtractor extractor = new WordExtractor(hwpfDocument);
            assertEquals("Hello POI", extractor.getText().trim());
        }
    }
