In the [text bubble constructor](https://github.com/google/blockly/blob/f8025a1bdd12025ecb8830159509148ff27ad3c8/core/bubbles/text_bubble.ts#L26), add a call to `dom.addClass` that adds a `blocklyTextBubble` CSS class to the `this.svgRoot`. This change should be made against the `rc/v12.0.0` branch. To work on this issue, comment below asking to be assigned.
