Build fails when appicon is an empty (but valid) svg after upgrade to 10.0.60

[3sRykaert]

Description

When using Maui 10.0.60 the following error occurs when building an app with an empty appicon:

'C:\Projects\MauiMemoryleak\MauiMemoryleak\Resources\AppIcon\appicon.svg'. System.InvalidOperationException: Cannot draw SVG file 'C:\Projects\MauiMemoryleak\MauiMemoryleak\Resources\AppIcon\appicon.svg'. The SVG has no size. Ensure the SVG includes a viewBox attribute or both width and height attributes with valid dimensions.

If I revert back to 10.0.51, the build works (this is the only difference between the build that works and the one that fails).
I think this is the cause: #33194
When I see the code changes on https://github.com/dotnet/maui/pull/33194/changes#diff-8f1fb2ce6396a186e797eb6f7f184f5b61e9afc6165f63bb102d566f68b91905 I think this is the correct fix:
(line 38-42 has to be moved to line 50 (so put it in the else))

note this is a duplicate from #35247 but I was able to add a reproduceable scenario, so the other issue may be closed & marked as duplicate.

Steps to Reproduce

1. build the project from https://github.com/3sRykaert/MauiMemoryleak/tree/EmptyAppicon
2. Watch the build fails

Version with bug

10.0.60

Is this a regression from previous behavior?

Yes, this used to work in .NET MAUI

Last version that worked well

10.0.50

Affected platforms

Android, I was not able test on other platforms

Affected platform versions

Every Android version I tested (and I think all other platforms also)

Did you find any workaround?

2 options found:

1. Revert back to older Maui versions
2. Instead of an empty (but valid!) appicon, use one with 1 transparent pixel:

<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<svg width="456" height="456" viewBox="0 0 456 456" version="1.1" xmlns="http://www.w3.org/2000/svg">
</svg>

becomes

<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<svg width="456" height="456" viewBox="0 0 456 456" version="1.1" xmlns="http://www.w3.org/2000/svg">
  <rect x="0" y="0" width="1" height="1" fill="transparent"/>
</svg>

Relevant log output

System.InvalidOperationException: Cannot draw SVG file 'C:\Projects\MauiMemoryleak\MauiMemoryleak\Resources\AppIcon\appicon.svg'. The SVG has no size. Ensure the SVG includes a viewBox attribute or both width and height attributes with valid dimensions.

This issue has been validated in Visual Studio Code 1.118.0 with .NET MAUI versions 10.0.60, 10.0.51 and 10.0.50. It can be reproducible on Android platform from 10.0.60.
