Berry persist.save() does not save changes to arrays

[andrew01144]

PROBLEM DESCRIPTION

A clear and concise description of what the problem is.

In Berry, persist.save() should save the new state of of an array to _persist.json if its state has changed.
It does not.
This used to work on V12.0.2.
Does not work on V14.2.0

Workaround: update a simple variable before doing persist.save().

• Set weblog to 4 and then, when you experience your issue, provide the output of the Console log:

TO REPRODUCE

Steps to reproduce the behavior:

I find this easiest to replicate by pasting each of these Berry lines, one at a time, into the Berry scripting console.

import persist
persist.a1 = [1,2,3,4]
persist.save()
# look at _persist.json - ok
persist.a1[2] = 44
persist.save()
# look at _persist.json - Error - a1[] has not been updated
persist.tx = tasmota.millis()
persist.save()
# look at _persist.json - ok, a1 has been updated
persist.a1[2] = 88
persist.tx = tasmota.millis()	# workaround, update a simple variable
persist.save()
# look at _persist.json - ok, a1 has been updated

EXPECTED BEHAVIOUR

A clear and concise description of what you expected to happen.

persist.save() should save the new state of a1[] to _persist.json if the state has changed.
This used to work on V12.0.2.
Does not work on V14.2.0

Workaround: update a simple variable before doing persist.save().
