Importing typography.html causes ie & edge to lose shadows and elevation

[chasb154]

Description

I've upgraded to Polymer 2.0, not hybrid. When using any element that imports typography.html from paper-styles, IE & Edge lose the shadows and elevations. Chrome and Firefox show not issues. I'm unable to test on Safari.

I started a project from scratch using polymer-cli and added a paper-card, paper-button, iron-icon and paper-input one at a time trying to find the problem. Paper-input caused the failure. I traced it to typography.

If I simply import typography.html in my shared-styles it causes the problem as well, so it isn't the paper-input element.

Expected outcome

Shadows and elevations should be unaffected.

Actual outcome

Shadows dissapear and all buttons and cards show only the text.

Live Demo

Steps to reproduce

1. Create a new Polymer 2.0 PRPL project from polymer-cli.
2. Add a paper-button or paper-card.
3. Import bower_components/paper-styles/typography.html in shared-styles or add paper-input to the page.

I did some more digging and it appears that it's the Roboto font from Google Fonts that's causing the issue.

If I comment out the following import link:

everything works. This link is in the roboto.html file which is imported in the typography.html file. Edge appears to have a problem with the Google Font Roboto.

[chasb154]

I tested a second site. It's not just the Robot font, it appears to be any Google font loaded with a link.

I tested further and it appears to be a timing/caching issue. If I comment out the Roboto font link in the roboto.html file and place it in the index.html file, everything works in Edge.

This issue happens to me too. However it's a lot of different styles breaking, possibly related to CSS variables.

It also happens with all Google Fonts. It works when putting the link-tag in the index.html.

Could this have something to do with polyfilled HTML imports having link-tags with rel="stylesheet" inside them?

Can you share the list of the installed bower dependencies?
You can check it with the command bower list | grep -v '│ ' (<-- bower doesn't have --depth=0 so this does the trick)

I noticed that polymer starter kit is still pointing to 2.0-preview branches for elements, and release candidates for both webcomponents and polymer.
After manually updating the bower dependencies and reinstalling them, I couldn't reproduce this problem (tried in MSEdge and IE). These are my installed dependencies:

├─┬ app-layout#2.0.0
├─┬ app-route#2.0.0
├── iron-flex-layout#2.0.0
├─┬ iron-iconset-svg#2.0.0
├── iron-media-query#2.0.0
├─┬ iron-pages#2.0.0
├── iron-selector#2.0.0

├─┬ paper-icon-button#2.0.0
├── polymer#2.0.1
├─┬ web-component-tester#6.0.0
└── webcomponentsjs#1.0.1

Here's my updated bower.json (with paper-button 2.0 added to the dependencies):

The paper-input or paper-dialog elements cause the problem. You didn't bring in paper-input or paper-dialog.

You will see the shadows from paper-button or paper-card disappear. My project worked at the stage yours is as well. It wasn't until paper-input or paper-dialog was added that things started to go haywire.

[valdrinkoshi]

I didn't include paper-input or paper-dialog because you didn't mention these previously.
I've added those dependencies but I can't reproduce the issue:

In this repository you can find my setup - https://github.com/valdrinkoshi/paper-styles-144

I deleted the bower_components folder and reinstalled.
Updates somewhere seem to have fixed the problem. Not sure what was updated to fix it.
