The flash line reserves one line of height, so a message that wrapped pushed the screen below it down. Every message is now at most 50 characters, one line of the popup's monospace font: the longer ones are reworded, and the ones that carried a wallet name or text from a server no longer do. The rule is written at showFlash(). A new end-to-end test drives the longest message and fails if the line's rendered height grows. It measures in the monospace font, which Firefox draws and Chromium does not. Model: opus-5-5
