getTagList returns incorrect result if tags are create after page loaded:

getTagList returns incorrect result if tags are create after page loaded (Hopefully we could get this in 8.10)

Steps to reproduce (as shown in the video below):

1. Remove all the tags
2. Visit Security Solution > Dashboards (It creates a Security Solution tag if there isn't one when landing on the page)
3. Observe that getTagList always return empty value even tags created.

Hey @angorayc , sorry I must be very slow.

In the video you show:

• Initially there are 3 tags in the drop down
• Then you go to a different tab and delete the 3 tags
• Then you go back to the previous tab, you refresh the page and show that there are no tags in the list

Isn't that what is expected? Not sure I see the issue.
Thanks.

It is possible that #160871 fixed this issue.
Let's re-verify after it is merged 👍

This issue requires #160540 to be merged to be able to test and debug it.

As discussed over Slack you found a workaround so we can de-prioritise it and I'll have a look in a future sprint.

Note to clarify the issue: this is an edge case where the page embedding the TableListView component creates a new tag when being accessed which apparently is not visible by the tag filter panel of the table.

In theory it should work as we fetch the tag list every time the tag panel opens (https://github.com/elastic/kibana/blob/main/packages/content-management/table_list_view_table/src/components/use_tag_filter_panel.tsx#L168 & https://github.com/elastic/kibana/blob/main/packages/content-management/table_list_view_table/src/components/use_tag_filter_panel.tsx#L83) which get the latest state of the tags cache https://github.com/elastic/kibana/blob/main/x-pack/plugins/saved_objects_tagging/public/ui_api/get_tag_list.ts#L11).

Looking at the security plugin code where the tag is being created I see in
https://github.com/elastic/kibana/blob/main/x-pack/plugins/security_solution/public/common/containers/tags/api.ts#L18

export const createTag = (
  { http, tag }: { http: HttpSetup; tag: Omit<TagAttributes, 'color'> & { color?: string } },
  abortSignal?: AbortSignal
): Promise<Tag> =>
  http.put(INTERNAL_TAGS_URL, {
    body: JSON.stringify(tag),
    signal: abortSignal,
  });

which is not using the tags client.

To solve this issue you need to create your tag using the saved_object_tagging plugin client (exposed from the start contract here https://github.com/elastic/kibana/blob/main/src/plugins/saved_objects_tagging_oss/public/api.ts#L25).
