Candidates for backporting to 3.4.x

[florian-h05]

These PRs are hot candidates for cherry-picking them to the 3.4.x branch:

I will only list PRs here, that have been tested in SNAPSHOTs (and some even the first milestone) for at least 2 wekks and no regressions were noticed in this time.

@openhab/webui-maintainers Can you please comment/vote?

@ghys WDYT?

@kaikreuzer WDYT?

Sorry @florian-h05, I only saw your comment here after triggering the 3.4.3 build.
But having a glance at those, I'd rate them "nice to have" but nothing really critical that we are missing in 3.4.3.

[florian-h05]

Can we cherry pick them for 3.4.4?

[kaikreuzer]

I'd leave this to you and @ghys to decide.

MainUI fixes:

• Fix redirection for reverse proxy with authentication not working #1670 (my PR, so I definitely need approval)
• Fixes WebAudio sink not playing on Safari #1765

To be considered in a few weeks after some extensive testing:

• Add a SSE reconnection mechanism #1807
• Show warning if SSE connection or send command fails #1808

I'm good with these 2 first PRs!

@ghys What do you think about backporting the third and fourth PRs to the 3.4.x branch?
They are battle-tested since their merge and no problems were reported.

[ghys]

Sure. I've seen the big "connection failure" banner flash up on occasion when reloading the page, which doesn't look too good IMHO. Maybe it should be shown with a delay e.g. 1/2 seconds, not immediately.

[florian-h05]

I will take care of that.

#1993 implements a 1 second delay.
