Display issues after upgrading to PM V34.X - Date picker and form fields not showing

[jerrylin333]

After upgrading to PM V34.X, I encountered the following issues in actual use:
Issue 1: Date picker on banking website
As shown in the screenshot, when checking transaction history on my bank's website,
the date selector displays correctly in PM V33.9X, but in PM V34.X the calendar dropdown doesn't render properly (see image comparison).
I have to manually input dates instead. Additionally, the transaction results table that appears in V33.9X doesn't show up at all in V34.X (either not generated or hidden).

Issue 2: Missing currency conversion field on shopping sites
On shopping websites I frequently visit, PM V33.9X displays a currency conversion field, but this field is missing or hidden in PM V34.X.
Since there might be other websites with similar element display issues, I've had to downgrade back to V33.9X for now.
Hope this feedback helps with debugging. Thanks for your work on PM!
This version uses natural forum language, clearly structures the problems, and maintains a respectful, constructive tone that's typical in bug reports

Thank you for the links! Very helpful information.

I noticed something interesting after reading the Pale Moon v34.0.0 changelog:
- v34.0.0 updated ICU to v78.1 (major internationalization subsystem update)
- v33.9.x worked fine with my banking site's date picker
- v34.x broke the date picker functionality

Could the ICU library update be related to this date parsing issue?
The old Firefox bug #1439800 was about date format parsing (dd-MMM-yyyy),
and it seems ICU handles internationalization including date formats.

Just wondering if this might help narrow down the issue.
Or should I continue using v33.9.x until this is addressed in a future release?

Thanks again for your help!

I hope this information is also helpful.

We're branching this bundle of issues over to #2952, as there's about a hundred and fifty changes to jsdate from our copy to ff's copy, and we need to determine which ones we want/need to include. I'm a bit focused going through the rest of the ICU-related bugs at the moment, to make sure there aren't any lower-level problems that these changes would rely on and be thwarted by.
