When you paste 3 characters into an input or textarea in which the text has length (maxlength - 1), it gets a length of (maxlength + 2), due to two spaces pasted before and after the pasted 1st character of the text. This can be reproduced in https://embed.plnkr.co/wHAtfCWA1IUi6oKlqc9Y/ or in this source code: <html><head></head> <body> qwe <input maxlength="3"/> </body> </html> Reproduction scenario: 1. Run the above code 2. Double click qwe to select it 3. Copy 4. Click in the textbox 5. Type aa 6. Press arrow left to position the caret between the a's 7. Paste Now the textbox contains: a q a This has length 5, while its maxlength is 3.
