Screenshots

Browser / OS

• OS: Manjaro Linux
• Browser: Firefox
• Browser version: 128.0-1

Additional information

This doesn't occur when sl-textarea has resize="auto" property.

I'm just guessing, but I have a feeling there's a problem here:

shoelace/src/components/textarea/textarea.component.ts

Lines 197 to 204 in c31d4f5

	private setTextareaHeight() {
	if (this.resize === 'auto') {
	this.input.style.height = 'auto';
	this.input.style.height = `${this.input.scrollHeight}px`;
	} else {
	(this.input.style.height as string | undefined) = undefined;
	}
	}

I can't reproduce this on Firefox 128 (macOS) with warnings shown.

@KonnorRogers are you seeing this warning?

@claviska I can reproduce it on FF 128.0

I see it now with the CSS tab selected.
