 Actually we used an `ExpandingTextArea` from `GemsFX` package so the content can occupy
 as much space as it needs in the `ScrollPane`.
 
 About the selection and copying, this goes down to fundamental issue from JavaFX.

+# Use `WebView` for Chat Message Content
+
+## Context and Problem Statement
+
+This decision record concerns the UI component that is used for rendering the content of AI summaries.
+
+## Decision Drivers
+
+Same as in [ADR-0036](./0036-use-textarea-for-chat-content.md).
+
+## Considered Options
+
+Same as in [ADR-0036](./0036-use-textarea-for-chat-content.md).
+
+## Decision Outcome
+
+Chosen option: "Use `WebView`".
+
+Some of the options does not support selecting and copying of text. Some options do not render Markdown.
+
+However, in contrary to [ADR-0036](./0036-use-textarea-for-chat-content.md), we chose here a `WebView`, instead of `TextArea`, because there is only one summary content in UI (when user switches entries, no new components are added, rather old ones are *rebinding* to new entry). It would hurt the performance if we used `WebView` for messages, as there could be a lot of messages in one chat.
+
+## Pros and Cons of the Options
+
+Same as in [ADR-0036](./0036-use-textarea-for-chat-content.md).
