Cursor moves to end of email input on Safari on input event

[StevenMeyer]

Description
If one tries to edit a text input's value from the middle (or start) of the value the cursor is moved to the end position for the next input. This is only on Safari web browser.

Reproduction steps

1. Open the playground using Safari
2. Enter a value (such as [email protected])
3. Move the cursor position to anywhere but the end (eg. before the @ symbol)
4. Start typing more than one character

Expected outcome
The new text should be entered at the cursor position and the cursor position should only move with the new input

Actual outcome
The first character is entered at the cursor position. The cursor is moved to the end of the input.

This is a duplicate of #36, but is still happening for us.

It's a problem with type="email" input elements. According to the spec these inputs don't have setSelectionRange() available.

A solution could be to, for email inputs only:

• change the type to text
• perform the setSelectionRange()
• change the type back to email

If my organisation decides that temporarily using a fork is preferable to fixing our cause for needing trim I may submit this PR myself.

That would be great!
