On Windows, clipboard text uses CRLF (\r\n) line endings which can cause newlines to be lost or displayed incorrectly when pasted via the {{CLIPBOARD}} variable.
Fixed by converting CRLF to LF before inserting clipboard text.
Fixes#19370
Fixes#19742 where file attachment containers did not inherit the chat direction setting, causing layout issues when typing in RTL languages like Persian.
Added dir={$settings?.chatDirection ?? 'auto'} to file container divs in:
- MessageInput.svelte (chat input file attachments)
- UserMessage.svelte (user message file display)
- ResponseMessage.svelte (response message file display)
- channel/Messages/Message.svelte (channel message file display)
The fix ensures file containers automatically detect and respect RTL text direction, maintaining proper layout alignment for RTL languages while preserving LTR behavior for Latin text.
The textVariableHandler was using URL.createObjectURL() for clipboard images, which created a blob URL instead of the required base64-encoded data URL. This caused an "illegal base64 data" error when sending messages with images pasted via a {{CLIPBOARD}} prompt.
This commit updates the handler to use FileReader.readAsDataURL() to properly encode the image, aligning it with the existing on:paste logic. Additionally, it adds error handling for navigator.clipboard.read() to address potential permission issues in Firefox.
When the "Valves" modal is opened from the "Integrations" menu, a click outside the modal would incorrectly close the integrations menu first. This was because the dropdown's outside click handler was still active.
This commit fixes the issue by introducing a `closeOnOutsideClick` prop to the `Dropdown` component. This prop is controlled by the `MessageInput` component, which now disables the outside click handler on the integrations menu when the valves modal is open, and re-enables it when the modal is closed.
