[3.0] - Join parameter bbb_hide_presentation_on_join inconsistent

[antonbsa]

Describe the bug
I first noticed when it failed on the Ci run of #19436. Running locally I could randomly reproduce the same behavior. It looks like sometimes it's being applied correctly, and sometimes it doesn't

To Reproduce
Steps to reproduce the behavior:

1. Create a meeting
2. Join a moderator with bbb_hide_presentation_on_join=true
3. Join an attendee with bbb_hide_presentation_on_join=true
4. Check session state: both users should join with the presentation minimized

Wrong behavior

I think bbb_hide_presentation_on_join doesn't exist anymore. It was replaced by userdata-bbb_hide_presentation_on_join. I've tried out userdata-bbb_hide_presentation_on_join=true locally and it worked fine.

Yes, the correct parameter is the one with userdata. I've checked on the test code and was able to confirm that we use the right parameter:

bigbluebutton/bigbluebutton-tests/playwright/parameters/parameters.spec.js

Lines 461 to 466 in 032ece8

	test('Hide Presentation on join @ci @flaky', async ({ browser, context, page }) => {
	const customParam = new CustomParameters(browser, context);
	await customParam.initModPage(page, true, { joinParameter: c.hidePresentationOnJoin });
	await customParam.initUserPage(true, context, { useModMeetingId: true, joinParameter: c.hidePresentationOnJoin });
	await customParam.hidePresentationOnJoin();
	});

bigbluebutton/bigbluebutton-tests/playwright/parameters/constants.js

Line 44 in 032ece8

exports.hidePresentationOnJoin = 'userdata-bbb_hide_presentation_on_join=true';

I'll retry to reproduce the reported behavior and comment below any new evidence
