Svg display probems with column-count property - html

Question

I have a list of blocks I want to display in multiple columns (at least 2 columns).
In my blocks I have a header with a title and a svg icon.
If I use the css property "column-count" to split content in columns, some svg disapear on Google Chrome. (no problem with Firefox)
Here is a demo :
section {
width: 500px;
margin-right: 100px;
float: left;
}
.container {
border: 1px solid black;
margin: 0 auto;
padding: 0.25em;
margin-top: 1.25em;
}
.container.withcolumns {
column-count: 2;
column-gap: 2em;
}
.block {
break-inside: avoid-column;
}
.block header {
font-weight: bold;
padding: 0.5em 0;
border-bottom: 1px solid grey;
}
.block header svg {
width: 15px;
height: 15px;
margin-right: 0.5em;
}
ul,
li {
margin: 0;
padding: 0;
list-style-type: none;
}
li {
margin: 0.25em 0;
}

Does anyone have an idea how to fix this?

Answer 1

I had the exact same problem and finally after searching for a while, the following made Chrome render my SVGs correctly:
-webkit-backface-visibility: hidden;
In your code above if you add the following, it works:
.block header {
font-weight: bold;
padding: 0.5em 0;
border-bottom: 1px solid grey;
-webkit-backface-visibility: hidden;
}

Answer 2

It's for sure a bug but here is a different code using the SVG as background to achieve the same without the bug:
section {
width: 500px;
margin-right: 100px;
float: left;
}
.container {
border: 1px solid black;
margin: 0 auto;
padding: 0.25em;
margin-top: 1.25em;
}
.container.withcolumns {
column-count: 2;
column-gap: 2em;
}
.block {
break-inside: avoid-column;
}
.block header {
font-weight: bold;
padding: 0.5em 18px;
border-bottom: 1px solid grey;
background:url('data:image/svg+xml;utf8,<svg xmlns="http://www.w3.org/2000/svg" viewBox="0 0 17.293 20" width="15"> <path d="M2674.323,1341a2.012,2.012,0,1,0-1.437-.575,2,2,0,0,0,1.437.575Zm1.52,1h-3.053a2.012,2.012,0,0,0-2.027,2v5.494h1.52V1357h4.067v-7.507h1.533V1344a2.022,2.022,0,0,0-2.039-2Zm-11.693-1a2,2,0,1,0-2.027-2,2.023,2.023,0,0,0,2.027,2Zm1.52,1h-3.04a2.015,2.015,0,0,0-2.04,2v5.493h1.533V1357h4.067v-7.507h1.52V1344a2.015,2.015,0,0,0-2.04-2Z" transform="translate(-2660.59 -1337)"></path></svg>') left top 0.5em/15px 15px no-repeat;

Answer 3

There is an error in your markup where you are closing the section before closing the last block. Still this is not fixing the problem.
This probably is a bug. In order to make it work I've removed the transformation and recalculated the d attribute.
section {
width: 500px;
margin-right: 100px;
float: left;
}
.container {
border: 1px solid black;
margin: 0 auto;
padding: 0.25em;
margin-top: 1.25em;
}
.container.withcolumns {
column-count: 2;
column-gap: 2em;
}
.block {
break-inside: avoid-column;
}
.block header {
font-weight: bold;
padding: 0.5em 0;
border-bottom: 1px solid grey;
}
.block header svg {
width: 15px;
height: 15px;
margin-right: 0.5em;
}
ul,
li {
margin: 0;
padding: 0;
list-style-type: none;
}
li {
margin: 0.25em 0;
}
