Internal links registered with core.chrome.setHelpExtension cause full page reload

[smith]

When adding a link to the upper-right help menu using core.chrome.setHelpExtension, links internal to Kibana cause a full page reload.

APM example:

kibana/x-pack/plugins/apm/public/setHelpExtension.ts

Lines 21 to 30 in bf73bcf

	{
	linkType: 'custom',
	href: url.format({
	pathname: http.basePath.prepend('/app/kibana'),
	hash: '/management/stack/upgrade_assistant',
	}),
	content: i18n.translate('xpack.apm.helpMenu.upgradeAssistantLink', {
	defaultMessage: 'Upgrade assistant',
	}),
	},

The expected behavior is a navigation without the full page reload.

We would just need to use application.navigateToUrl in a onClick handler in addition to the current href

Changing from bug to enhancement, as I missed that it was already possible to work around that by manually providing an onClick handler
