Please note that the last "splice" rule will never match [in the latest
Squids]. Other than being misleading about your true intent, this should
not cause problems.
Apart from the pointless splice rule, this is the configuration variant
you should focus on if you want to bump everything.

Perhaps the browser lacks the SubCA certificate? Does Squid send that
intermediate certificate to the browser? You should be able to tell by
examining the browser-Squid SSL handshake in wireshark.

Please note that the second and third rules will never match [in the
latest Squids].
Also, the above config variation is subject to Bug 4327 [in the latest
Squids]. It is not yet clear what the correct Squid behaviour should be
in this case. Avoid this configuration for now.

Possibly because of the problems discussed in comments 0-3 of the Bug
4327 report mentioned above. I do not know whether your Squid version is
affected because quite a few things have changed since it was released.

I cannot fully explain this observation. In theory, this last config
should have similar effects to your first config, but should handle
fewer cases because the last config lacks SNI support.
I recommend that you try to reproduce the problems [with the first
config] using the latest v3.5 daily snapshot (or trunk):
ssl_bump stare all
ssl_bump bump all
Good luck,
Alex.
