What

When a key sequence arrives split so that only a bare Escape (or Escape-bracket) is left in the buffer, the decoder now remembers that fragment and joins it to the next chunk, emitting one key or mouse event instead of a stray Escape followed by stray literal characters.

Details
  • The remembered fragment is cleared as soon as a complete sequence arrives.
  • It is not applied inside a paste, so pasted text is unaffected.
Evidence

flushedEscapePrefix

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
