Failed parsing 'srcset' attribute value since its 'w' descriptor is invalid.

Problem/Motivation

Currently calculating the image width from its styles/effects may lead to float/decimal values, which then results in the following messages in the browser:

Failed parsing 'srcset' attribute value since its 'w' descriptor is invalid.
Dropped srcset candidate "/path/to/image.jpg?itok=XXXXXX"

The corresponding srcset then contains values like:

/path/to/image.jpg?itok=XXXXXX 1371.2w

Steps to reproduce

  • Create an image style that calculates its scaled width by its height and use an image that would result in a float/decimal value width, when height is used as base

Proposed resolution

  • Round the width values used in srcset to integers

Remaining tasks

  • Create issue fork and MR to fix this issue
