Bug is present in all previous version of MarginNote 4. Text selection with mouse in epub files can only expand, but not shrink (by dragging in the opposite direction) the selection. Bug is not present when interacting with PDF files.
On a related (and more serious note), after I attempt text selection in an epub file, version 4.1.13 (11300) hangs on macOS 15.2 (24C101) Apple M2. This bug needs to be investigated and fixed right away. This does not trigger when selecting PDF files. Spin dump attached
