PDF exhibiting the bug

When I open the attached PDF in LibreOffice Mac, it highlights some words containing the letter "f" as misspelled: first, office, flashing, findings.  Other words containing "f" aren't highlighted.

The "f" doesn't appear to be some identically-looking Unicode variant of the letter.

That is related to ligatures (fl, ff, fi). Reproduced on

The spellcheck is correct, the fi, fl, ffi etc are not the regular letters but presentation ligature code points (U+FB01, U+FB02, U+FB03) which are legacy charcaters that shouldn’t be used in text. The bug here, if there is one, would be in PDF import that should have resolved these to the regular characters.
