Highlighting makes all freeze sometimes

[ymeine]

Image you have a template whose content is:

{Template {
    $classpath: "..."
}}

Now put the cursor at the very end, and keep pressing backspace. When you reach this state precisely:

{Template {
    $classpath:

Everything freezes (there is a lot of errors in the console by the way when debugging).

Another example:

In an empty document, try typing {{X (even if this is probably not a valid syntax). The X will never appear because of freezing.
