The flash line reserves one line, so a message that wrapped pushed the screen below it down. #flash-msg no longer wraps: text too long for it is cut with an ellipsis, and showFlash() puts the whole message in its title. Every message is also reworded to at most 50 characters so none is cut, and the add-token screens flash a fixed line for any error other than the two lookup messages, logging the detail. A new end-to-end test writes a message several lines long into the line and fails if the line or the screen below it moves. Model: opus-5-5

// Parsing for the dust threshold field in Settings.
|
|
//
|
|
// Pure: no DOM, no state, so the accepted set can be unit tested directly
|
|
// instead of through the settings view.
|
|
//
|
|
// Accepted input is plain decimal digits only, meaning a whole number of
|
|
// gwei, zero or greater. Zero is a real setting: it hides nothing.
|
|
//
|
|
// Deliberately rejected, not coerced:
|
|
// "" nothing to save
|
|
// "-1" a negative threshold has no meaning
|
|
// "1.5" fractional gwei is not a threshold the filter can use
|
|
// "100 gwei" the unit is already printed beside the field
|
|
// "0x10" hex, which Number() would silently read as 16
|
|
// "1e3" exponent notation, which Number() would silently read as 1000
|
|
//
|
|
// The last two are the reason this is a digit test and not a Number() test.
|
|
// Number() accepts both, and accepting them would put a number in the field
|
|
// that the user did not type — the same silent substitution the visible
|
|
// rejection message exists to end.
|
|
|
|
// Must render on ONE line of #flash-msg; see showFlash() in
|
|
// src/popup/views/helpers.js for how long that is.
