Bug
Certain interpolations are being broken into multiple spans. For example in a template we have
{{ctrl.variableName}}.

In Chrome, Firefox, Safari, Edge this always becomes Text associated with variable

but in IE11 in CJK languages this is becoming {{ctrl.variableName}} which displays on our page as the variable.

There are several places this bug is displayed in production for our site but I will include steps to reproduce for just one of them.

To reproduce:

1. Go to https://console.cloud.google.com in IE11
2. Click the hamburger menu in the top left -> click API Manager
3. Click Credentials in the left side nav (if you're prompted to create a project click "Create")
4. Click "Create credentials" -> "API Key" -> "Server Key" -> "Create"
5. Go back to the Credentials Page and click on the name of your new API Key
6. Click the vertical "..." in the top right -> Preferences -> Language and regional formats
7. Change the language to a CJK language (Japanese for example) and click Save
8. The page will reload. Observe the {{ctrl.key.currentKey}} and other variables displayed in the page.

Here is a screenshot of the issue:

** Details **
This is a bug specific to IE11 (and earlier IE). I'm using IE version 11.0.10240.16603 on Windows 10 Enterprise. We are running angular 1.5 but this also occurred in 1.4
