Parser fail with numerical and logical AND about xonsh

[PodioSpaz]

I have only been able to replicate the problem when using fully qualified paths. No problem with relative paths.

This works...

/🔒
❯ cd tmp/123 && ls

This works...

~
❯ cd ../../tmp/123 && ls

This does not...

/🔒
❯ cd /tmp/123 && ls

Reproduced in an alpine:edge container:

<user>@bf5102635826 / # mkdir -p /tmp/abc /tmp/123 /tmp/a123
<user>@bf5102635826 / # cd /tmp/abc && ls
<user>@bf5102635826 /tmp/abc # cd /tmp/a123 && ls
<user>@bf5102635826 /tmp/a123 # cd /tmp/123 && ls
xonsh: For full traceback set: $XONSH_SHOW_TRACEBACK = True
NameError: name 'cd' is not defined
<user>@bf5102635826 /tmp/a123 [1] # echo / 123 && ls
xonsh: For full traceback set: $XONSH_SHOW_TRACEBACK = True
NameError: name 'echo' is not defined

And with XONSH_SHOW_TRACEBACK = True:

<user>@bf5102635826 / # cd /tmp/123 && ls
xonsh: To log full traceback to a file set: $XONSH_TRACEBACK_LOGFILE = <filename>
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
NameError: name 'cd' is not defined

<user>@bf5102635826 / [1] # echo / 123 && ls
xonsh: To log full traceback to a file set: $XONSH_TRACEBACK_LOGFILE = <filename>

I'm new to Xonsh. But "while all Python code is also xonsh, not all Bash code can be used in xonsh", I believe the correct behaviour is to change the && into a Python and.
https://xon.sh/tutorial.html#logical-subprocess-and

These errors occur with || too. And when replacing && with and, the echo treats the and as an arg, but the cd raises a different error:

<user>@bf5102635826 ~ # cd /tmp/123 || ls
xonsh: To log full traceback to a file set: $XONSH_TRACEBACK_LOGFILE = <filename>
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
NameError: name 'cd' is not defined

<user>@bf5102635826 ~ [1] # echo /tmp/123 || ls
xonsh: To log full traceback to a file set: $XONSH_TRACEBACK_LOGFILE = <filename>
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
NameError: name 'echo' is not defined

<user>@bf5102635826 ~ [1] # echo /tmp/123 and ls
/tmp/123 and
<user>@bf5102635826 ~ # cd /tmp/123 and ls
cd takes 0 or 1 arguments, not 2. An additional `-P` flag can be passed in first position to follow symlinks.
