Before: Given two sets of hover documentation, a) longer text (more lines) and b) shorter text (fewer lines).. when moving from a) to b), the extra lines from a remain in the buffer. After: With this change, the buffer is cleared before adding new hover text, thus removing the excess trailing lines from any previous hover text.
