Warpified Docker bash subshell causes warp icon in dock to bounce consistently

Discord username (optional)

Describe the bug

The Warp Terminal icon on the dock would bounce consistently on an interval (every ~25s) when a warpified bash subshell is active and the focus is away from the terminal.

This seems to only happen when the warpified subshell is bash. When I tried it wish zsh it did not cause the icon "bounce" behavior.

To reproduce

I've reproduced it consistently whenever I open an interactive docker bash shell and warpify it. Here are the minimal steps to reproduce:

1. Make sure you have Docker running
2. Run docker run --rm -it alpine in Warp
3. Install bash in the alpine container: apk update && apk add bash
4. In another pane in Warp, open a bash shell into the container: docker exec -it <container_name> /bin/bash
5. Warpify the subshell
6. Change the focus away from Warp
7. Icon starts bouncing at some consistent interval

Related Notes:

• It seems to add a new line to the first alpine shell running, that could be related.
• When I enable the bell sound in Warp, it makes the sound whenever the Warp icon bounces

Expected behavior

The icon should not bounce or make sounds when a Warpified subshell is running.

Additional context

I'm not sure if this is a new bug or regression, but I only started noticing since I recently wanted to do some shell work inside docker containers and activated the Warpified subshell.

Does this block you from using Warp daily?

No

Is this a Warp specific issue? (i.e. does it happen in Terminal, iTerm, Kitty, etc.)

Yes, this I confirmed this only happens in Warp, not other terminals.

None

No source files or tests are identified. Start by reproducing the Docker bash and Warpify steps, then compare the behavior with zsh while observing the dock bounce, added line, and bell sound; done means the active Warpified bash subshell produces none of these notifications.
