Question pane overlay blocks/dims the conversation text behind it #23515

What happens

When the question tool renders a pane with multi-select options, the pane is a floating overlay that covers part of the conversation behind it. The covered text is dimmed but remains the primary source of context for the question being asked.

On top of that, notification popups (e.g. "Question -- Next steps planning a question / Go to session") can appear in the corner and overlap the question pane itself, obscuring option labels and descriptions.

Net effect: the user is asked to make a decision based on context they can no longer fully read, and sometimes can't fully read the question either.

Why this matters

Question panes are used most heavily in planning/decision moments where the agent's preceding analysis is exactly what the user needs to weigh the options. Hiding that analysis forces the user to either:

1. Dismiss the pane, read the context, then hope to find the same pane again (not always possible);
2. Type an out-of-band answer asking the agent to wait while they read;
3. Guess and hope the recommended option is right.

Repro

1. Have the agent produce a substantial analysis block (e.g. cost breakdown, diagnostic findings).
2. Immediately follow with a question tool call presenting multi-select options whose rationale depends on that analysis.
3. Observe: the analysis is dimmed and partially covered; any subsequent notification popup can further obscure the pane.

Expected

• The question pane should not cover substantive conversation content, OR
• The pane should be collapsible/moveable so the user can reveal the context behind it without dismissing, OR
• The dimmed content behind the pane should remain fully legible (no overlay tint), OR
• Notification popups should not overlap modal question panes.

Environment

• OpenCode Desktop v1.14.19
• Windows
