PG&E billing page is broken on Safari Tech Preview 20

[Ryosuke Niwa]

Reproduction steps
1. Go to https://m.pge.com/
2. Log in to your PG&E account
3. Open billins

Expected result:
I can see my bill & pay it.

Actual result:
Blank page is shown (with headers & footers)

On Safari 20, I'm seeing the following JavaScript error:

Actually, I no longer have an active PGE account, so I'm probably the wrong person to test this.

However, the behavior I'm seeing is a blank page on both El Capitan's Safari and on STP 20. So this might not be a regression (and it could be a bug on the website itself).

In Chrome, I get a message that shows up saying that my account is longer active.

That's interesting. I can open the billing page on the system safari (10.0.2).

I have a PG&E account, but I'm not sure what to click after logging in. The bills are just PDFs that get downloaded as files.

I'm not sure if I'm getting exactly the same result, but it looks quite similar. On trunk, I'm getting a blank page (with headers and footers) even on https://m.pge.com main page - I cannot log in.

I don't see anything like this with shipping Safari/WebKit, so it does look like a regression. I didn't try El Capitan for shipping Safari/WebKit, only Sierra.
