Further notes

[kantlivelong]

Wouldn't this be more of a "pre connect delay" which would be satisfied by "postOnDelay" ?

[Gifford47]

Yes, technically, actually. I also had trouble with the naming at first. Since I originally took the code from the author, the "post" refers to the action after the button is pressed.
Maybe it depends on how you look at it :)

Feel free to rename it :)

Pretty much break/fix for now.

My PR is now tested over 1 year with no further issues. Can you merge it?

[paccerdk]

Please merge.
There's currently a handful of forks, dealing with this particular problem.
Judging by that, this seems to be the main problem that people actively deal with - this is a problem that needs fixing.

I've been applying this patch manually for the last year while waiting for a merge (since this is what is in the plugin repository)

If the repository isn't actually going to be maintained (as in, merge pull request for fixes) please let us know.
