Pressing Tab key in centered bullets causes odd behavior

Hi Julian,

We are noticing odd behavior when pressing the Tab key in centered bullets in a WPTools editor. Replication steps:

1) Click the icon to center justify text,
2) Click the "Bullets" icon,
3) Begin typing text,
4) Press the Tab key,
5) Note the text jumps to the left margin,
6) Type another character, other than a Tab character,
7) Note the text jumps back to centered text.

Is this a bug, or is there a property we need to change on the editor?

We are using WPTools version 5.30.1.

Thanks,
