Expected Behavior
In Firefox, the input box should dynamically adjust its height to accommodate the expanding text content, ensuring proper alignment.
Actual Behavior
After sending the first prompt using Ctrl+Enter, the input text box stops automatically resizing to fit the content.
Steps to Reproduce
Go to OpenWebUI in Firefox.
Type something in the prompt box.
Press Ctrl + Enter to send your prompt.
Type more into the prompt box.
See that the box doesn't get taller anymore.
The box only works correctly again after you refresh the page.

Thank you for your bug report. I can confirm this behavior in Firefox, but it doesn't have anything to do with the Ctrl-Enter send setting. It also occurs with the default setting for me.
I think the issue comes from https://github.com/open-webui/open-webui/commit/7c68a424f8
After submitting the prompt, this code adds a static height of 28px to the input box.
Chrome still grows the input box to the intended height (because of min-height: fit-content) whereas Firefox (136.0) does not adjust the height to the content.
You can see this by comparing the following simple HTML example in Chrome and Firefox (see also screenshots). I am not a CSS guru and don't know what the correct behavior is.
@tjbck Do you still remember why you added this change?

Hello @tremlin. That appears to be a red herring, as adding the Ctrl + Enter feature encourages us to send multi-line prompts more frequently. Thank you for investigating! I've updated the title to better reflect the defect.
I noticed that Chrome also calculates the height as 28px, but it doesn’t visibly affect the UI. In contrast, Firefox explicitly sets the chat Input box height to 28px as the CSS style, making the issue more noticeable.
@tjbck Could you please provide some insight as we noticed there's multiple commits related to the chatbox height adjustments. Thanks!
