Kibana i18n Setting Leads to Unknown saved object type Warning

[Serendo]

Kibana version:
6.8.4
Elasticsearch version:
6.8.4
Server OS version:
centos 7.5
Browser version:
safari
Browser OS version:
macos 10.14.6
Original install method (e.g. download page, yum, from source, etc.):
yum
Describe the bug:
when switched to zh-CN using i18n setting in kibana.yml, there is a warning message coming up when browsing saved objects in kibana management section. This is caused by the i18n translation of the savedDashboard's title in savedObjectManagementRegistry(src/legacy/core_plugins/kibana/public/dashboard/saved_dashboard/saved_dashboards.js).
Steps to reproduce:

1. Make a dashboard, it can be an empty one.
2. Set i18n.locale: "zh-CN" in kibana.yml
3. Start kibana and go to management -> saved objects.

Expected behavior:
There will be a warning message which means the Dashboard is an unknown type of saved object.

Screenshots (if relevant):

Errors in browser console (if relevant):
No errors in console
Provide logs and/or server output (if relevant):

Seems like this is actually a @elastic/kibana-platform or @elastic/kibana-app issue, as the saved object management page is using the translated name to do the saved object lookup.
