Edge Beta intermittently ignoring IE Mode

This is happening to us currently (it wasn't happening as of 2 weeks ago) and I can recreate it at will. chrome_debug.log pasted into Word doc below. I can't find any smoking gun causing it but I can cause it easily. On the log below you can see it loads one of my IE mode sites on line 1558, but when I try the exact same site 3 minutes later on line 1781 it loads it in Edge mode. I tested on the current Beta edge (87.0.664.18) and it is still occurring on it.

wbabbit Hi - Thanks for reaching out!

The IE Mode team has been investigating. Would you be able to try run MS Edge with the command --disable-features=msUsePrerenderNTP and see if that fixes the problem?

Let us know if that helps! Thank you!

Also, there have been some other discussions about this on a separate thread (Re: Problems with Enterprise Mode (IE Mode) in recent builds ? - Microsoft Tech Community), if you want to take a look.

Kelly_Y It looks like that resolves the issue, I haven't been able to make it occur in the last 45 mins and generally it took me 2-3 minutes to make it happen prior.

  wbabbit Thanks for testing! I will let the IE Team know that it seems to resolve the issue in your case. We'll follow up with any updates as their investigation continues.

    wbabbit Hello! Good news! Just heard from the IE Mode team that the next update being released to MS Edge Stable V86 should include the fix.
