The details

Resolves

Fixes N/A

Proposed Changes

Makes the text input bubble css consistent with the workspace comment css. Yay for styling.

Test Coverage

Manually checked that everything still looks correct in LTR and RTL.

Documentation

Will need to start documenting CSS classes somewhere.

Additional Information

If/when we move the workspace comments into a plugin, we'll need to do something with the CSS for the resize handle because right now the text input bubble is relying on it. One option is to just move that CSS into the text input bubble class.

Breaking changes / To fix

If you were using the blocklyCommentTextArea CSS class to style comment icons, you should use .blocklyTextInputBubble .blocklyTextArea instead.

If you were using the blocklyResizeSE CSS class, you should use .blocklyResizeHandle instead.

If you were using the blocklyResizeSW CSS class, you should use .blocklyRtl .blocklyResizeHandle instead.
