I would suggest to add something like the following
menuitem:not([acceltext]) {
padding-inline-end: 16px !important;
}
to make the right side of some menus as follows look better on version 139 and above:

Otherwise the right-ends of these menu’s text would be way too close to the right border. The exact value of padding-inline-end to add in the above sample, however, was just a quick example of mine to show the effect, not necessarily the best practice.
