• I have provided every relevant configuration, setting, and environment variable used in my setup.
• I have clearly listed every relevant configuration, custom setting, environment variable, and command-line option that influences my setup (such as Docker Compose overrides, .env values, browser settings, authentication configurations, etc).
• I have documented step-by-step reproduction instructions that are precise, sequential, and leave nothing to interpretation. My steps:
• Start with the initial platform/version/OS and dependencies used,
• Specify exact install/launch/configure commands,

• Describe all options and toggles enabled or changed,
• Include any files or environmental changes,
• Identify the expected and actual result at each stage,
• Ensure any reasonably skilled user can follow and hit the same issue.

Expected Behavior

Should forward all input (especially in code blocks) to the LLM

Actual Behavior

Only parts of the input is properly forwarded, some of the input is removed

Steps to Reproduce

1. Write this exact message:
   repeat this expression:

< [Registration date] = {">=$(=$(vMaxMonthStartINCWithParamMonth))<$(=MonthStart($(vMaxMonthEndINC)))"}, [Registration day] >

(Problem appears with or without code-block).

2. See problem, LLM outputs:

< [Registration date] = {">=$(=$(vMaxMonthStartINCWithParamMonth))

3. Write same expression to file and provide it as text to the LLm in chat (or through open-terminal) and LLm can properly read it and see the full expression and will repeat it properly

Logs & Screenshots

1. 🟣 #16612 feat: disable "Rich Text Input for Chat" by default because it corrupts input
   This reports that Rich Text Input can corrupt pasted text and special characters, which matches the new issue’s symptom of input being altered before it reaches the model.

2. 🟣 #17958 issue: Tab characters in text pasted into chat textbox are removed after submission
   This is another input-corruption bug in the chat textbox, showing that pasted content can be modified on submission; it is related to the broader class of lossiness in message forwarding.

3. 🟣 #9759 issue: rich text input
   This older issue also describes prompt text being altered, with newlines and XML-like tags removed, which is very similar to the new report about parts of an expression being cut off or removed.

4. 🟣 #18175 issue: Multi-lines input variables (text area) do not render properly in the conversation
   Although it focuses on predefined prompt textarea variables, it documents loss of line breaks when content is rendered into chat, which is adjacent to the same text-preservation problem.
