When an HTML field is present in form layout and it has an empty/NULL value, GlideScriptRecordUtil.getChangedFieldNames function always returns a value that includes the HTML field, even though no changes has been made.

The issue started to occur in Jakarta. The scenario works as expected in Istanbul.

1/ Create a Business Rule
table: Problem
advanced: true
when: before
update: true
script:
(function executeRule(current, previous /*null when async*/) {

var gru = GlideScriptRecordUtil.get(current);
var changedFields = gru.getChangedFieldNames();
gs.log(changedFields,"testlog");

})(current, previous);

2/ Go to any Problem record which has some Description.
3/ Update the Short Description and Save (while the Description isn't empty) .
-- Go to <instancename>/syslog_list.do?sysparm_query=source%3Dtestlog
The latest log's message is [short_description]

4/ Clear the Description field and Save.
-- Go to <instancename>/syslog_list.do?sysparm_query=source%3Dtestlog
The latest log's message is [description]

5/ Update the Short Description again and Save(this time the Description is empty) .
-- Go to <instancename>/syslog_list.do?sysparm_query=source%3Dtestlog
Actual result: The latest log's message is [short_description, description]
Expected result: The latest log's message is [short_description]

6/ Save the record without updating any field.
-- Go to <instancename>/syslog_list.do?sysparm_query=source%3Dtestlog
Actual result: The latest log's message is [description]
Expected result: There shouldn't be any log printed
