This is the right fix but there's one additional problem: Help is listed as the plugin to which many other plugins need to tabified next to. For instance:

spyder/spyder/plugins/pylint/plugin.py

Lines 30 to 38 in 141f0fb

	class Pylint(SpyderDockablePlugin):
	NAME = "pylint"
	WIDGET_CLASS = PylintWidget
	CONF_SECTION = NAME
	CONF_WIDGET_CLASS = PylintConfigPage
	REQUIRES = [Plugins.Preferences, Plugins.Editor]
	OPTIONAL = [Plugins.MainMenu, Plugins.Projects]
	TABIFY = [Plugins.Help]

So, please look for all those instances and add Plugins.VariableExplorer to that list. And if it's not a list, please make it one.

Finally, after doing that please rebase on top of the latest 5.x to get the fixes to our tests.

Sorry about that i thought i rebased earlier today, but maybe my branch didn't pull in correctly.

[hmaarrfk]

PS. i feel like i am updated on the 5.x branch

I pulled in #22237 to let the tests run successfully

Thanks, but the PRs against 5.x are merged to master as well. So, your extra PR wasn't really necessary (sorry if I wasn't clear enough about that).
