tims b1375ab946 project_panel: Fix crash when adding a new file or directory to the first folded directory (#23217) ... Closes #23216 This crash happens in the `update_visible_entries` function, where we calculate `ancestors` and `current_ancestor_depth`. `ancestors` is map storing information about folded ancestors and `current_ancestor_depth` is basically selected ancestor index in reverse order of visibility. For example, before adding a new file or directory in `a/b/c`, the `ancestors` might look like: ```jsonc { "entry_id_of_c": { "current_ancestor_depth": 2, // "a" is selected "ancestors": ["entry_id_of_a", "entry_id_of_b", "entry_id_of_c"] } } ``` When new file or directory is added to`a`, ancestors length is reduced, as `a` now is not part of folded dir due to having multiple children. But depth still remains the same as while calculating it, we use depth from `old_ancestors` to preserve selection across renders. This causes panic. ```jsonc { "entry_id_of_c": { "current_ancestor_depth": 2, // wrong: use of old depth here causes panic "ancestors": ["entry_id_of_b", "entry_id_of_c"] // correct: notice "a" is missing, as "a" now has multiple children } } ``` This PR fixes it by capping depth so it don't exceed `ancestors` array. This preserves existing depth as well as handles our edge case. Release Notes: - Fixed crash when adding a new file or directory to the first folded directory		2025-01-16 23:34:44 -07:00
