Description:
When using the Chrome extension to look up Chinese words or phrases, the pop-up dictionary sometimes provides a definition that only references another word or phrase, without offering a direct explanation. This is not helpful when I don’t know the referenced word.

Example:
I moused over the phrase 無可厚非, and the pop-up displayed see 未可厚非. This forces me to look up the referenced word separately, interrupting the flow of understanding.

Expected Behavior:
The dictionary should provide a direct definition or explanation for the word or phrase being looked up. If cross-references are necessary, the pop-up should also include an explanation alongside the reference.

Steps to Reproduce:
1. Install the Chrome extension.
2. Navigate to a webpage with Chinese text.
3. Mouse over the phrase 無可厚非.
4. Observe the pop-up definition referencing another word or phrase without an explanation.
