* Prevent inline image previews from displaying when Neovim is in Insert or Select mode. * Hide the image preview when the cursor is positioned within the source text range of the concealed expression. * Refresh the concealment state immediately after image placements are updated to ensure visibility rules are applied instantly.
* Simplify cursor range checks for concealed inline images * Hide image previews if the cursor is on any line covered by the range * Explicitly include 'math' type images in the concealment hiding logic
* Introduce `M.match_at_cursor` to return the full image match object, decoupling it from the old `M.at_cursor` function. * Update `M.at_cursor` to use the new matching function, maintaining backward compatibility while simplifying the original implementation. * Prevent image hover popups from appearing in non-normal modes, ensuring the hover window only shows up during navigation. * Ensure float windows are created when `Snacks.image.config.doc.float` is true, regardless of the `inline` setting, allowing simultaneous use of inline placeholders and hover previews.
- Calculate the buffer position corresponding to the end of the image range. - Position the hover window relative to the range end when the image has defined delimiters. - Ensure the image preview does not overlap the closing delimiters of the source expression.
- Update image documentation hover when the cursor moves in insert mode by listening to `CursorMovedI`. - Allow documentation hover windows to remain visible in insert and select modes. - Refine inline image concealment logic to only hide images in insert or select mode if they are explicitly marked for concealment.
- Conceal the image placement when the cursor enters the text range it represents. - Apply cursor-based hiding logic in Normal mode to allow editing of concealed source text. - Prevent hiding images that belong to inactive or non-current buffers during updates.

Previously, after a LuaSnip expansion(entering Select mode), the inline preview image ends up covering the code(i.e. latex) content. 
The luasnip: parse({ trig = "sum", name = "sum" }, "\\sum_{n=${1:1}}^{${2:\\infty}} ${3:a_n z^n}"), |
