Is there a way to use the bold math macro \bm together with wide accents such as \widetilde or \widehat, without generating a too wide accent?

\documentclass{article}    
\usepackage{bm}

\begin{document}
$\widetilde m$
$\widetilde{\mathbf m}$
$\mathbf{\widetilde m}$
$\bm{\widetilde m}$
$\widetilde{\bm m}$
\end{document}

    Ugly, but there is this: $\widetilde{\textit{\bfseries m}}$ – Steven B. Segletes Aug 10 '20 at 10:56
  • Indeed, both solutions, adding a new command defining a small widetilde as well as avoiding bm all together, fix my problem. However I was looking for a less manual/more robust solution, that can not be broken so easily by my coworkers. – Jan Hajer Aug 10 '20 at 11:05
  • You seem to think that the problem is caused by bm but that's not it: \widetilde exists in different sizes, and it just happens that \bm{m} is wide enough to make \widetilde choose the larger version. This would happen with any symbol/letter/whatever which is wide anough. – campa Aug 10 '20 at 11:18
  • @campa good observation, one can play with \widetilde{\rule{10.001pt}{3pt}}, 10pt gives the small one, 10.001pt does not. – daleif Aug 10 '20 at 11:31
  • Thanks for the clarification, I did not realize that the width of the character has changed beyond a critical threshold due to the bm package handling bold italic fonts correctly. – Jan Hajer Aug 10 '20 at 12:06
  • An obvious followup question would be: Can I change the thresholds? – Jan Hajer Aug 10 '20 at 12:13
