Subject: [PATCH] fix(image): clear conceal_lines when hiding placements

When hiding an inline placement (e.g. cursor in a math block), `_render`
cleared `conceal` but not `conceal_lines`. Tall math environments use
`conceal_lines` for leftover rows below the image, so those lines stayed
hidden while editing.

Fixes #2569
