Is it permissible for a woman to uncover her face to kiss the Black Stone while men are around her?

Kissing the Black Stone is a confirmed Sunnah during circumambulation (Tawaf), if it can be done easily without jostling or causing harm. If it is not possible, then one must refrain and suffice with pointing to it with the hand, especially for women. Likewise, it is not permissible for a woman to uncover her face while kissing the Black Stone due to the presence of non-mahram men.
