Description
Bug report
Bug description:
When obtaining input using the input function, syntax highlighting is being applied on the echoed stdin.
Notably this does not occur when reading input via sys.stdin.read.
tested on nix and uv builds of python3.14 - though I doubt it has any effect with regard to this issue
CPython versions tested on:
3.14
Operating systems tested on:
Linux

Research direction
Reproduce the behavior on Linux with Python 3.14 by comparing input with sys.stdin.read. Inspect the REPL handling of echoed stdin and determine why syntax highlighting is applied only for input. Done means echoed stdin from input is displayed without syntax highlighting, while the existing sys.stdin.read behavior remains unchanged.
