RFR: 8295248: JEditorPane HTML form with multi selection broke drawing after reseting [v2]

[Toshio Nakamura]

> When JEditorPane shown HTML form with multi-selection, the reset operation broke its drawing.
> 
> There are two issues. The current method `OptionListModel.removeIndexInterval()` disabled selections, but it didn't fire the change. Then, no re-drawing. Another issue is the method works as remove and shift. Then, selection values were corrupted.
> I think the clear method `OptionListModel.clearSelection()` is suitable here.
> 
> Test: jdk_desktop on macOS (x64, Monterey), Linux (x64, RHEL8), and Windows (x64, 2012R2).
>       No regression found
