Sorry to necro a thread, but please give us this! So much time wasted and often text lost from my (windows) computer registered ctrl + x twice and therefore obsidian dumping the highlighted selection I’d just cut to do a blank line instead.
VS code has a setting to prevent this: "editor.emptySelectionClipboard": false
Please for the love of accessibility for everything from fine motor control issues to wonky laptop keyboards that inconsistently register key presses, add the setting to prevent obsidian from adding empty lines to the clipboard.
