Bad characters when exporting SSH private key via CLI

This issue also occurs in the following scenario.

Generate the SSH Key using the browser extension ( Chrome, Windows 10 ). For example, this can be done when adding a key to Bitbucket in the browser. The extension will automatically suggest creating an SSH Key, even though you can't create one directly through the browser extension ( requires 1Password 8 ). Note that the name of the item can't be edited which is inconvenient. It can be edited later in the desktop app.

Next, from a linux (Ubuntu) box with op installed with apt, execute any of op run, op read, op inject. Surprisingly, a carriage return ( \r , ^M ) is included on some lines, making it unusable without further processing.

Is this due to creating the key from a Windows browser?

Can op detect the OS it is running on and reconstruct the key with the appropriate line endings?

Stripping carriage returns downstream of op is inconvenient.

Thanks!!!
