• This font-weight change is only applied in the .monaco-workbench .part.sidebar > .sidebar-footer ... scoped rule. The unscoped .account-widget-account .account-widget-account-button rule (used in component fixtures/other contexts that don’t have the full sidebar DOM structure) will keep the old weight, which can lead to inconsistent rendering between the real UI and fixtures. Consider mirroring the font-weight in the unscoped rule (or refactoring to avoid duplicating the rules).

.monaco-workbench .part.sidebar > .sidebar-footer .account-widget-account .account-widget-account-button {
	overflow: hidden;
	text-overflow: ellipsis;
	min-width: 0;
	font-weight: 500;
}

.account-widget-account .account-widget-account-button {
	overflow: hidden;
	text-overflow: ellipsis;
	min-width: 0;
}
