Can't switch to buffers in another tab

[bgerstle-lookback]

Steps:

1. Open FileA
2. Open FileB in a new tab (e.g. :tabe FileB)
3. Executed :CommandTOpen e FileA (or select from :CommandTBuffer list)

Expected results:

vim switches to FileA.

Actual results:

vim opens FileA in current tab.

.vimrc is setup via my dotfiles. I've added the set switchbuf=usetab, and CommandTOpen works for buffers in split panes, but not buffers in another tab.

Thanks for the report, @bgerstle-lookback. Something tells me this is a regression, as I don't recall this happening in the past.

Likely suspects: 85949ce and/or 595976e.

Back from my personal account 😅 Confirmed that this is a regression: rolling back to 5.0.0 restored CommandTOpen functionality.

I think I know what's wrong. I'll push a fix in a bit.

Sometimes I do desire the bugged behavior. Can it be made available somehow?

Why do I want it (not all the time, but sometimes)?

Let's say I have this layout where I'm editing file2 in tab1 while giving a look at related files file1 and fileX

_______________________     _______________________
|tab1                 |     |tab2                 |
-----------------------     -----------------------
|         |           |     |         |           |
|  fileX  |           |     |         |           |
|         |           |     |         |           |
|---------|   file2   |     |         |   file4   |
|         |           |     |         |           |
|  file1  |           |     |  file3  |           |
|         |           |     |         |           |
-----------------------     -----------------------

then I go to tab2 where I have to edit file4 while giving a look at file3 and fileX (the same as the other tab).

Usually I'd move to tab2-file3 (well, this can be done with the non-bugged version of the functinality you fixed here, ahahah), hit Ctrl-ws, and then use this plugin to open fileX. However, since fileX is already opened in the other tab, the focus jumps there.
