Cannot disable splashscreen on browser

Ionic version:

Ionic CLI : 5.4.4
Ionic Framework : @ionic/angular 4.11.2
@angular-devkit/build-angular : 0.803.2
@angular-devkit/schematics : 8.3.2
@angular/cli : 8.1.3
@ionic/angular-toolkit : 2.1.1

Current behavior:

I’m using my ionic code for both browser (as a normal website, not wpa) and mobile apps. On browser I would like to disable the splashscreen because it is a losing of time on browser and I dont like it on desktop.
I tried a lot of solutions but none works.

Expected behavior:

Not showing the splashscreen on browser.

Related code:

I tried adding this to the config.xml

<preference name="SplashMaintainAspectRatio" value="true" />
<preference name="FadeSplashScreenDuration" value="0" />
<preference name="SplashShowOnlyFirstTime" value="false" />
<preference name="SplashScreenDelay" value="0" />
<preference name="SplashScreen" value="none" />
<platform name="browser">
    <preference name="ShowSplashScreen" value="false" />
</platform>

They are totally ignored.

Have you found a solution? same problem here.

Not yet, and seems like the Ionic team avoids to reply to inconvenient questions.
I asked also about a problem with scroll not detected by the browser (browser tab not hidden on scroll) and they avoid to reply too.

indeed, i thought so too.
in the meantime i found a solution, i’ll just copy paste my uncleaned stuff, i let you remove what you don’t want:
put this in config.xml:

    <platform name="browser">
        <preference name="AutoHideSplashScreen" value="true" />
        <preference name="SplashScreenBackgroundColor" value="white" />
        <preference name="ShowSplashScreen" value="false" />
        <preference name="SplashScreenWidth" value="152" />
        <preference name="SplashScreenHeight" value="152" />
    </platform>

and then, copy paste config.xml in www/ after the build (if www is served by your backend as it is for me). then, if you want to turn on the splashscreen on browser, be sure www/ also contains the folder and image for it (i had to make a script that does: ionic cordova build browser --prod, cp config.xml www/config.xml, and cp the image as well in www/)

Works!! Thank you!!
Maybe exists a way to include the config.xml automatically with the build
