A CLabel is used to support the display of the icon next to the text. Unfortunately, CLabel has it's own way to handle the display of it's contents when there is not enough space. From the documentation of CLabel:
https://www.ibm.com/docs/en/rational-soft-arch/9.6.1?topic=SS8PJ7_9.6.1/org.eclipse.platform.doc.isv/reference/api/org/eclipse/swt/custom/CLabel.html

"If there is not enough space a CLabel uses the following strategy to fit the information into the available space:

• ignores the indent in left align mode
• ignores the image and the gap
• shortens the text by replacing the center portion of the label with an ellipsis
• shortens the text by removing the center portion of the label"
