Notes field mangles saved notes (rendering/storage sanitisation issue)

When I use either speech-quotes (") or slashes (/) in a banking reference note, the note is saved but upon re-accessing it, I see that it is either stored or rendered with mangled sanitisation.

I understand that the notes field component is a HTML text-area and therefore the values cannot contain certain characters (otherwise setting the value of the text-area to those characters would mangle the rendering of the Web page), but why isn’t the data rendered using HTML entity characters?

For example, if my note is:

'Sent by James using quote reference "ABC/001"'

It seems that either the data is escaped incorrectly and stored as:

'Sent by James using quote reference \"ABC\/001\"' (note the escape characters creeping into the note)

Or it’s being rendered in my Web browser as that. I expected the server to preserve my notes and use HTML entities to render them safely in the text-area component, e.g:

'Sent by James using quote reference ""ABC/001""'

Please see attached screen-shots demonstrating the issue:

I’ve passed this to our development team to take a look. Someone will update you shortly.
