Problem is apparently the Fingerprint Protection ← for both financial websites.
Duh. And, thank you.
Interesting: After the price field displays completely, and IF Fingerprint Protection is re-enabled . . . the price field continues to display completely, including after a reload of the webpage.
Of course, after restarting Brave Browser, I have to disable Fingerprint Protection, in order to display the complete price field.
UPDATE (20251121-1757 EST Friday)
I get a similar graphics display issue / problem when visiting a website that tests whether or not WebGL is working:
When there, Brave Browser does not display the test website’s rotating cube, until I disable the site-specific Brave Shields Fingerprint Protection.
