Thunderbird Calendar shows incorrect time for America/Santiago

Clocks went back one hour in Santiago, Chile last week and Thunderbird does not recognise the new time, although Windows (10) does.

The calendar line show the current time to be one hour ahead of the time on Windows; i.e., the Windows time has updated correctly, but the calendar time has not. Adding non-local events to the calendar causes them to be displayed one hour ahead of the correct time.

Changing the calendar setting to use the system timezone, or use America/Santiago has no effect that I can see.

Typing Date() in the error console of Thunderbird gives the correct time, as per Windows.

This also happened in the last time change here in Chile.

How can I fix the Calendar to see the same time as Thunderbird and Windows?

Months on and this problem still persisits. I discussed this with colleagues, and some have the same problem and moved away from Thunderbird Calendar, while others used to have the problem but don't have it any more. Nobody has any idea what the cause is, or how to solve it.
