Backspace, delete, cut broken?
While composing a tweet or reply, as of yesterday pressing backspace or delete, or either of those or ctrl+x with some text selected, has no visible effect. The text stays the same. The selection stays the same. The only way I can get rid of text is to select it then type something else to replace it. But, if I do anything after a failed delete then click post, then what ends up posted is an amalgamation of what I saw in the box when I clicked post, what I had previously tried to delete, what was before or after the cursor when I tried to delete, etc.
Anyone else?
