chromium 151 (snap version) does not offer vertical tabs without experimental flag

Hello,

I have chromium 151 (snap version) installed on ubuntu.

This version of chromium does not offer the vertical tab feature unless I enable the experimental flag. Any other version of chrome/chromium I use offer vertical tabs without the experimental flag.

Not a big deal to enable the flag, I was just wondering why is this version of chromium lagging behind and what else might be removed from the general release...

Any feedback appreciated, googling the subject only returns instructions how to enable the flag, this question is beyond that.

Thanks.
