Given the following HTML:
<input type="range" onblur="console.log('blur')">
1. If a user focuses on the first input, then presses tab twice, "blur" is logged
2. If a user clicks the first text input, then clicks and alters the range input, then clicks the second text input, nothing is logged
Other browsers correctly fire onblur when using the mouse.
Example on codepen:
The element doesn't get the blur even because it's not focused with a mouse interaction.
