AHA! I just found something out that may answer this question. The "Holy Spirit" in Hebrew (רוח הקודש) and Aramaic (רוחא דקודשא) is feminine, and regularly referred to by using feminine pronouns.
Solomon's wisdom was given him by God (1Kings 3:5-12; 4:29-34), and this wisdom is from above (James 3:17),, as Luke's was (Luke 1:3). Also, Solomon did not lose it, for it remained with Him (Ecc.2:9).
