recover email draft from hung gmail tab

I composed an email draft in gmail. After closing the draft and wanting to inspect it in “Drafts” gmail hangs with a “Loading…” sign.

I opened gmail in another tab and the draft isn’t there, but I can see that the tab where I composed the draft still has some knowledge of it: the counter for the “Drafts” folder is visible and greater by 1 than in the freshly opened tab.

I’ve tried turning the wifi on and off and getting gmail out of its funk by opening/closing messages and trying again, but it always ends up hanging as soon as I pressed “Drafts” or “Sent”, etc.

I’m wondering, could there be a may to recover the draft by using the dev tools on the hung tab? Like crawling the dom and looking for string fragments that the draft contained? Could anyone suggest some code?
