Wrong price upon selecting product options after switching currency

[eldonbite]

Encountered an issue when selecting product options using the swatches in product details page wherein the price of the item in a previously selected currency gets displayed instead of the corresponding price in the currently selected currency. Disabling Block HTML cache type seems to prevent this issue from happening.

Preconditions

1. Magento 2.1.x
2. Store supports multiple currencies
3. All cache types are enabled

Steps to reproduce

1. Select a currency (e.g., GBP) then view a product's details:
   
2. Select product options in the current product details page :
   
3. Switch to a different currency (e.g., JPY):
   
4. Select a product variant; the price reverts back to the previous currency's value but with the current currency's symbol:
   

Expected result

Correct equivalent price in the current currency should be displayed

Actual result

The price in the previously selected currency gets displayed

Updated to Magento 2.1.3 and it seems the issue has worsened. When switching to JPY, the correct price briefly shows up, then suddenly gets multiplied resulting to a very high product price.

Price in AUD after clicking product options:

Price in GBP after clicking product options:

Price in JPY upon page load:

And then after a few seconds or once the document is completely loaded:

Also having this issue.. Upgraded to Magento 2.1.3 and getting really odd prices until you select a swatch. Using configurable products w/ swatches and multi-currency. Unlike @eldonbite , it's still happening for me when I disable block cache.

edit: actually, sometimes choosing a swatch doesn't fix the price..

@dthampy There's already MAGETWO-62682, which should be the same as MAGETWO-60977, no?

@erfanimani, MAGETWO-62682 created for tracking #7941 is a duplicate.
