Can bold dotless i and j be displayed in Libertinus Math?

Currently, when the font is set to Libertinus Math, $bold(dotless.i)$ and $bold(dotless.j)$ aren’t displayed as bold:

#show math.equation: set text(font: "Libertinus Math")

$bold(dotless.i), bold(dotless.j)$

$bold(i), bold(j)$

Is there some way to display these dotless characters in bold, as intended? I think the font may allow these to be displayed because the documentation for the LibertinusT1Math LaTeX package includes an example of $\mathbfit{\imath}$ being displayed properly (in the table on page 3).

(I want to be able to do this so that I can display the unit vectors î ($bold(hat(dotless.i))$) and ĵ ($bold(hat(dotless.j))$).
