v0.86.2

Fixed

• A flame-graph tooltip stays inside the viewport, and stops growing past it. A frame's detail is its raw message — a query frame carries the whole SQL, a the_content frame the rendered HTML — so on a real record the tooltip ran to dozens of lines. Taller than the space below the cursor it flipped above, and taller than the space above it ran off the TOP, where nothing can scroll it back: the first lines were simply unreachable. The label is capped at 30 lines with a … N more lines marker, the box takes a max-height of the viewport and scrolls inside it, and the flip is clamped at both edges rather than only the bottom.
