Unexpected closing of tabs

[rockstorm101]

Left-clicking on tabs sometimes closes the tab. How and when exactly it happens I can't say for sure. I tried enabling the close button (had it disabled by default) but it didn't make a difference. Steps to reproduce:

1. Open two documents. Each gets their own tab. Now the second tab is focused.
2. Left-click on the first tab. Now the first tab is focused.
3. Left-click on the second tab. The second tab is (unexpectedly) closed.

My expectation was that on step 3, the second tab got focused instead of closed.

Is this a bug? If this behavior is to be expected, is it something I can disable somehow? It is pretty annoying.

Many thanks in advance. Let me know if you need more information/debugging.

I have this case reproduced if the active buffer is a dired buffer. Is it the same for you?

Not sure to be honest. I've tested this with markdown files. Which I don't think open as dired buffers? In case it is relevant, I'm using markdown-mode. No Emacs expert here, so please bear with me.

This is happening to me as well when using org-mode

I also have this problem. According to describe-key, what's happening is:

There were several key-sequences:

  <tab-line> <down-mouse-1> (translated from <down-mouse-1>) at that spot runs the command mouse-drag-tab-line
  <tab-line> <mouse-2> (translated from <mouse-1>) at that spot runs the command centaur-tabs-do-close

Those are influenced by `mouse-1-click-follows-link'

What appears to be happening, is that Emacs is translating mouse-1 to mouse-2 thinking that the tab is an ordinary link. If mouse-1-click-follows-link is set to nil, the problem seems to disappear (at least for me).

Another way to get rid of the problem is to nuke centaur-tabs-do-close:

 (defun centaur-tabs-do-close (event)
     (interactive "e")
     (centaur-tabs-do-select event))

Since the issue has been open for more than a year, I assume it's probably not going to be addressed. Can I suggest instead that the function centaur-tabs-do-close be "nuked" from the centaur-tabs code base, as a work-around?

Sorry for the late reply. I'll look into this!
