Failing test test_dev_tool_export_dashboard_by_id_from_space

[jsoriano]

This test fails since some change in the stack, it was found in automated PRs for snapshots used in testing, seen at least #29275 (master) and #29277 (8.0), it seems to work with older images.

The test is: libbeat/tests/system/test_dashboard.py::Test::test_dev_tool_export_dashboard_by_id_from_space

We have to confirm if this is expected due to some breaking change in 8.0, or if this is an actual issue.

I've been working on this in the background as way to understand the system tests. This test starts failing somewhere between these two versions of Kibana:

Status	Container	Date	Commit
PASSES	kibana:8.0.0-3d27fc14-SNAPSHOT	2021-10-21	6c52cce0b854b144794d3278b23358d77c1e0592
FAILS	kibana:8.0.0-0ab1fe1f-SNAPSHOT	2021-10-29	2424ff2879acc18cb6c4e58a5ffa3efa69e313ed

I haven't had a chance to bisect further to find the commit where it starts failing.
